Hey Les -

I haven't tried this but were you looking at /dev *after* you did the 
chroot?  It sort of makes sense to me that the running kernel would only 
populate it's /dev, not the chrooted /dev.  Rescue mounts at least the 
root partition under /mnt/sys (or something like that).  Before you 
chroot, you should probably also mount any other partitions you want 
under /mnt/sys and then chroot.

Cheers,
Dave
