OK, I know the problem.  You're installing GRUB to a partition rather than
your MBR.  Apparently, it doesn't have room in the boot record of your partition
to install the Stage1.5 file for ReiserFS, so it needs to use the blocklist
method for loading the kernel.  However, ReiserFS is not compatible with the
blocklist method unless you mount the boot partition with the notail option
before copying over the GRUB files.  You can fix this by:

1.  Boot Gentoo Linux with your boot disk
2.  mount /boot -o notail
3.  mkdir /tmp/grub
4.  mv /boot/boot/grub/* /tmp/grub
5.  mv /tmp/grub/* /boot/boot/grub
6.  umount /boot

Now, you should be able to use the bootdisk (or the grub program under Linux)
to set up your boot sector.  Of course, now that everything is using ext2
(which doesn't need the notail option), you're all set.

What I didn't notice immediately is that you're using GRUB as a secondary (not
a primary/MBR) boot loader.
