A lot of people edit /boot/grub/grub.cfg directly, you have to add it right before the "set root". In my case I followed the instructions of the Gentoo MBP wiki (http://en.gentoo-wiki.com/wiki/Apple_Macbook_Pro)
WARNING: if you follow this method, you won't be able to resume after suspend. I have a MBP 8,1 as well and I can suspend fine (have to unload "b43" module first). I finally was able to use AHCI mode after suspend by booting from grub-efi (You might want to check this bug: https://bugs.launchpad.net/mactel-support/+bug/817017)

Short instructions:

- lspci -vnn|grep SATA

- Take down the number of your IDE/SATA controller (something like
8086:3b28)

- Create "01_mbp_ahci" in "/etc/grub.d/" (The mbp_ahci part can be
changed, but 01 is important)

- Paste this in the file:
#!/bin/sh -e
echo "setpci -d XXXX:XXXX 90.b=60"
(where XXXX:XXXX is the number you took down previously)

- Make it executable (the wiki does not mention it, but I'm pretty sure it's necessary)
sudo chmod u+x /etc/grub.d/01_mbp_ahci

- Run update-grub
