It depends upon the perspective, doesn't it? Sure might seem like a rip-off to package the JTAG separately if you only plan to buy one unit.
But, maybe if you've got something to sell to the public, you buy 100 Plugs and one JTAG port. That way, you don't have to pay for the FDDI chips, etc. for all the sale units.

Hopefully, you have not thrown away the Linksys end connector. On the Linksys box, there is a little diagram which will tell you (probably) that the center part of the connector is positive and the outer portion negative. That will lead to two options.
The first is to cut the end connector plug and find which wire is attached to the center.
Or, you could buy a small outlet to match the external power supply plug, drill a hole into the sheeva box and install that outlet, then just solder the old PSU wires to the matching elements of the new outlet. This would avoid the need to cut the Linksys wires.
If you do not have the connector, then your best bet is to check with a cheap multimeter. Normally, the wire with the identifying element (printing, or the raised ridge) is the positive wire. But, one never knows if the kid in China or Malaysia followed the standard. I would not make any connections just because it is supposed to be a certain way.

Let's make it simpler.
Connect with the method that gave you the Marvell> prompt. Leave that connection attached and the serial terminal window open.
If you connect in time to see any text, wait until that finishes and report what is shown.
If you do not see any text, then press the return ("enter") and see if any text appears.
If nothing appears, use a paper clip in the little hole by the SD card slot to reset the Plug. Report what text appears, and where the process stops.
Until we can know the state of your machine, it is impossible to try to help.

Your last post did not clearly state your problem.
If you cannot connect with ssh, you will need to use a terminal server to connect. If the Sheeva is not even on the network, there will be no other way to connect.
What do you mean you tried all the programs on the How To?
On what screen do you "just see a white page?"
Why and when do you "press ctrl-c?"
If you are able to see the Marvell prompt, why do you not allow the machine to try to boot completely?

There really isn't anyone working full-time, or even a-lot-of-the-time on the the wiki at present. (I am still hoping to do more, but Life happens). So, it is unlikely that someone will immediately respond to your request to "fix the page."
You may not feel that you want to invest the time to re-write that page. But, if you would be so kind, to put a small note on top of the page (not just on the discussion -- go ahead and jump in there). That way others can have a stronger warning and avoid the problems you encountered.
For that matter, what you could probably help with is a wiki page describing the problem you encountered, and what you did to correct the problem. Of course, if you were not keeping records, you might not feel as if you can describe it accurately.
Thanks for trying to help.

Yes, the more symptoms you describe, the more it begins to sound like the power supply problems reported by others. Might be a matter of days before it goes out completely.
Any chance you are on 240V A/C main power?
Or, have you some device connected to the USB port, taking power from the Plug?

Does anyone know what offset the U-Boot env config lives at for a GuruPlug?
I don't see anything obvious at 0xa0000 in my nanddump of /dev/mtd0.
In Flash: 0x0 to 0xa0000 UBoot 0xa0000 to 0x100000 Reserved for U-Boot variables 0x100000 to 0x500000 (4 MB) uImage 0x500000 to 0x1fb00000 (507 MB) Root file system
