Seems your initrd wasnt loaded by the bootloader.. . Do you have an initrd on your $bootdevice? To start with the new kernel, I used the dd image from TS with a debian root fs and initrd...
Make sure you have CONFIG_BLK_DEV_ RAM and CONFIG_BLK_DEV_ INITRD selected.
Also note that 2.6.28 doesn't support your nand at all! This means your kernel cant boot the root fs from nand...

Alexander's wiki has more tipps about resolving boot problems:

I think your problem its not kernel related...

Bye
