/dev/hda would not work, it  complains that the /dev/hda is not a block
device....

well, if that's exactly what your problem is,  try these:

>>  change  your BIOS settings, make your ide devices displays at the top of
you device >> list, that is, your CDROMs shows before your hard disk.., or
do the reverse..

>> or try to add a kernel options in your grub.conf. something like this:
>> kernel (hd0,6)/kernel-2.6.13-gentoo-r13 irqpoll root=/dev/sda9

can't remember all details now, hope that helps.. good luck..
