Does passing the parameter no_wb=1 to the radeon kernel module help?

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

Alternatively, does disabling the integrated RS780 GPU work around the problem?

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 :)
