I am getting a "Bad Data CRC" error when trying to start the Debian installer via TFTP.  I have the pingtoo uboot:
Marvell>> version
U-Boot 1.1.4 (Dec 27 2009 - 22:03:21) Marvell version: 3.4.27 - pingtoo patch.01

Following the instructions at http://www.cyrius.com/debian/kirkwood/sheevaplug/install.html, I start a TFTP install, but get the Bad Data CRC error before it gets properly started:

Marvell>> setenv bootargs console=ttyS0,115200n8 base-installer/initramfs-tools/driver-policy=most
Marvell>> bootm 0x00800000 0x01100000
## Booting image at 00800000 ...
   Image Name:   Debian kernel
   Created:      2010-02-12   1:37:09 UTC
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    1811896 Bytes =  1.7 MB
   Load Address: 00008000
   Entry Point:  00008000
   Verifying Checksum ... Bad Data CRC
Marvell>>

Am I missing something? Could I have a bad sheevaplug? Does the size of 1811896 bytes look right? The md5sums of the uImage and uInitrd are:
fd00b21042762034d0ba62b29ca938d8  uImage
ba8ce369dab181d073a875344ec41d82  uInitrd

Many thanks for any suggestions anybody might have,

I somehow got a bad download of the uI* files - the md5sums should be (for those dated 12-Feb-2010 01:37 at http://ftp.uk.debian.org/debian/dists/unstable/main/installer-armel/current/images/kirkwood/netboot/marvell/sheevaplug/):

5f7a03ac43a2a076298edc4ee85f0348  uImage
ba8ce369dab181d073a875344ec41d82  uInitrd
