0.32, you said that might be the problem - what version is better (newer or older)?
update:
tried bzImage2.6.35.7.KS and it is not able to mount nfs / network unreachable so likely does not support the nic
also tried bzImage3.8.8core - same errors - unsupported bios, but by the way is also showing no partitions found. I think the stock 0.32 bzImage shows that same message.
so in fact maybe something to do with the disk format or mode?
