I've installed other distributions of Linux before on a MacbookPro and have found that installing GRUB to the boot record of sda is a Bad Idea. Instead, try installing GRUB to the partition that Gentoo is currently on (or wherever your /boot partition is mounted) such as (hd0,3). Also, make sure that GRUB is compiled with support for the filesystem that you desire to use; I know for a fact that you have to have a particularly new version of GRUB to support EXT4 filesystems.
