--- Comment #18 from James Tyrrell james@tyrrells.com 2012-04-09 20:15:22 PDT --- What would it take to get this patch into mainline? Like I said before I have a MacBook Pro 8,3 and the patch works for me, allowing me to boot via EFI and use the Radeon graphics card to power my Apple Thunderbolt Display. This is something that was only possible when booting via BIOS.
