Altboot stopped working

Late versions of altboot fail to boot for me:

I've tried loading them from memory and from flash and both fail.
This seems to affect all the latest snapshot binaries, I didn't have
any older builds to test with except the last one Frank Wille sent me
with the change to the SATA-driver so I'm not sure when it stopped
working.
I tried that old version and it worked, naturally.

There was some change 2 weeks ago acording to the webcvs to altboot
that might be the cause. Anyone else have similar problems?
