Correct, but possibly cramfs isn't selected at all anymore. Not sure.

Eh? That's completely new to me.

I've always installed Etch, and Lenny, and now Squeeze generic images
without needing any such trickery... And I've never seen any other
reports of anybody else doing that either.

Either because the drivers for those file systems are not available, or
because of changes in the upstream kernel code between .18 and .26...
But IMO that's not really relevant. It seems to me that there must be
something subtly wrong in your configuration of how D-I gets loaded which
results in the failure to load the standard initramfs initrd.
I think it's better value for money trying to track that down than
worrying about file systems that should not be needed at that stage.
In other words: I think you're trying to work around the symptoms instead
of solving the cause.
