It's the same in that once you have a working kernel inside domU, you
can use it by changing xen config file to use pygrub. That is:
- in domU config file, comment-out "kernel" and "ramdisk" line, change it to
bootloader="/usr/bin/pygrub"
- in domU, create a file /boot/grub/menu.lst or /boot/grub/grub.conf
which has contents similar to this

default=0
timeout=5
hiddenmenu
title RHEL5-xen-domU
        root (hd0,0)
        kernel /boot/vmlinuz-xen ro root=/dev/hda1
        initrd /boot/initrd-xen.img

- make sure domU's initrd has xenblk if it's compiled as module
instead of built-in.

Now the actual kernel package, content of grub.conf, and initrd would
be different in Gentoo.
