hacked-up radeon VFCT BIOS access patch
So the good news is that a VFCT ACPI table does indeed show up when I boot
under UEFI native mode on the HP EliteBook.
I hacked up some code to get the BIOS from there and it successfully brought up
the card and drove my DisplayPort screen. (hack patch attached)
The bad news is that the LVDS panel first went backlight-off, on starting X
started displaying flickering pixelgarbage and at some later point the entire
box locked up.
I'll go diff the BIOS images against each other, maybe the BIOS from VFCT is
corrupted...
