--- Comment #9 from Jeremy Huddleston <jeremyhu at freedesktop.org> ---
BTW, copying /sys/kernel/debug/dri/0/vbios.rom to /lib/firmware when in
BIOS-emulation mode has allowed me to get nouveau loaded when in pure EFI mode
via:
$ sudo modprobe nouveau config=NvBios=vbios.rom
However, there's some really bad screen flicker with the 3.13 kernel from
Ubuntu 14.04.3. It looks as though the screen is refreshing at about 60Hz and
every other frame is all black (issue doesn't happen in the BIOS-emulation mode
on the same kernel).
I'll give a newer kernel a try.
Here's from the successful load:
