the hard drive is in fact pata and not sata or scsi?
linux file systems were compiled into the kernel to support the file systems 
on the
partition(s)? --- what is in your fstab???
you installed/have one windows one linux one swap partitions?
or
you installed/have one windows/ one linux boot/ one linux root/ one swap 
partitions?
or
???

Suggest you boot the install cd

mount /dev/hda2 /mnt/gentoo    ---this will report the file system used
ls -l /mnt/gentoo

determine whether it is a root or a boot directory.

ls -l /mnt/gentoo/boot

should contain file: bzImage-2.6.14 which should be exact spelling of your 
kernel name if grub.conf is correct    what kernel install method did you 
use? my kernel names always look like kernel-2.6.13-r5 after following the 
handbook

suggest delete:

root (hd0,1)
setup (hd0)

from grub.conf
