Well, the problem was caused by # grep -i bootl /etc/genkernel.conf BOOTLOADER="grub" setting 'BOOTLOADER="grub2"' fixes the problem. Feel free to close as invalid, but I suggest changing the default value from "grub" to "grub2" because grub2 is now stable (default) on Gentoo.
I have attached a patch to bug 577484 to change the default, I'm going to go ahead and close this one out since that change plus the impending removal of grub legacy should make this moot
