It doesn't seem to help. `dmesg | grep WB` shows it as Disabled, but modprobe
still hangs on load at the RS780 firmware.

Works. With the RS780 GPU disabled, everything functions.

BIOS -> Advanced Chipset Features -> Surround View -> [Disabled], KMS works, no
modprobe hang.

I didn't know that that card could be switched on and off. Thanks :)
