initrd requires block deive support. I want to cut that entirely, too.

LILO should be OK now, with the new bootloader protocol which prevents it
from stomping on the EBDA. Grub will hopefully be driving DoC directly,

As far as I know, it should work now, but it doesn't use the ECC. You only
get the normal JFFS checksumming, and I haven't yet modified it to cut
down the number of writes.

This is a very useful thing to do, I agree.
