make an rdev on your kernel to see if it has the right root device:
$rdev vmlinuz
should give you :
$Root device /dev/hdb2
else you can change it also with rdev ( look at the man page)
Besides this, the exact procedure with dd worked for me fine.
I had the same message once when I forgot to compile scsi support into my
kernel (I have scsi disks), but this can't be the problem if you can boot
the kernel normally.
