Oh, sorry, I didn't realize you were talking about GRUB Legacy (this
list is mostly about the development of GRUB 2). I think you are
missing some "initrd" (GRUB2) or "module" (GRUB1?) line after the
"linux" (GRUB2) or "kernel" (GRUB1) line - and the genkernel line
should not be in the GRUB config files at all. The exact boot
parameters and configuration should be in the Gentoo documentation: if
I remember my Gentoo times correctly, the Handbook should have all the
info you need. If you mail me a link to the post related to this issue
in the Gentoo forums, I can answer you better than in this list.
