The card is consist out of two Radeon M9 chips connected to a PLX
PCI-PCI bridge. I noticed an interesting difference in the BCTRL
register reported by the non working version and by a older computer
with X7.0 that works.

The non-working version that hangs the machine has a BCTRL value of
0x000A (S_SERR_L & VGA_EN). I don't know if S_SERR_L is a standard
register name, but the PLX databook says; "Secondary System Error: Can
be driven LOW by any device to indicate a system error condition."

The working (non-crashing) system has a value of 0x000C (ISA_EN &
VGA_EN) 

Could this be a problem, i saw you added some check for a Intel bridge,
could the same hack maybe also be needed for this bridge ?
