cbxbiker61: Thx! ppp works like a charm and now i can connect to teh internets with ZTE MF636

Ps. Did you disable the Highspeed operations (haven't tested the SD Card yet with this kernel)?

Sounds good. I also stumbled upon some problems with 3G modems since there's no modules for ppp. Not sure if i'm the only one experimenting with 3G modems heh? Cheers!

Disabling highspeed operations would be appreciated (to get reliable SD support)...

Would this solve the -110 errors when using rootfs from the SDHC Card? I'm able to boot the system from the SDHC but when using the system for a while (1 or 2 mins), i get bunch of -110 errors and then system crash. I'm currently testing Transend 4GB SDHC card.
I'm using 2.6.30-rc7 kernel currently and everything else seems to work OK.
