Boot to your previous kernel in recovery mode.  You don't need X.  Run:

# sudo update-initramfs -k CURRENT-KERNEL

It can't hurt, and works for me.  This has happened to me 4 times so far.  
The problem is not that it can't find the root partition (or at least, not 
only - I can modify that in grub and get a slightly different error).  It 
doesn't find the filesystem drivers.  I'm betting your root FS is not 
ext2/3.

Damn.  I see Nils has suggested essentially this, and hasn't even had to fix 
the problem himself!  Good call Nils.  I would suggest not using the "-k 
all" option, though, because you don't want to risk breaking the kernel you 
_have_ managed to boot from.
