Hei Alex,

while we are talking about xorg loading radeon driver twice again...do
you by chance have a hint about my completely crashing system when i try
to use the internal together with a pci radeon? My guess is that xorg
messes something up while pci scanning or so... is something known about
that?

In detail:
With primary display set to AGP in the BIOS i can only make the agp
radeon work (even a singlehead pci layout would crash).
With primary display set to PCI in the BIOS i can get the PCI radeon
work as singlehead, but as well not both PCI and AGP together.

The symptom is a completely hangup system (not only X), even the xlogs
are not finished to be written, so they don't give any reasonable clues.

André.
