Unable to boot with debian kernel 2.6.15

[Wouter Lueks <wouter@telox.net>]

It's been some time since I updated my kernel.  I'm currently using a
self-compiled 2.6.12 kernel.  It thought it was time to check out the
stock debian kernels since the seemed to be working very good for a lot
of people.

So I went ahead and installed the debian kernel and hoped it would boot. 
However, no matter what I try I keep getting the following error:

"VFS: unable to mount root fs on unknown-block(0,0)"

The root-fs is XFS, and the xfs module is included in the initrd module. 
I couldn't find any major differences with other yaboot.conf files, so
I'm a bit at a loss on how to solve this.

Regards,
