Try to force the Radeon driver into PCI mode. Under Linux doing this stops the blank screen and locks.

This was to give Jean some (indirect) access to a powerpc64 (PowerMac G5) Radeon context for some radeonkms development. (Jean had been hoping to get my card going in that context.) We got to the point that a kldload for radeonkms did not complain/refuse but the display was then munged up and the driver could not find the Video BIOS. The fact that it is a Radeon X1950 for the video hardware may make it odder than usual for PowerMac G5 Radeons. But it is the only Radeon that I have access to for G5's.
