Note that controlfb most definitely has nothing to do with your problem.
There's some PCI funniness with control indeed, but since that graphics
adapter is on a separate PCI bus from your ATI card, they
_cannot_ interfere on the PCI level.

Was that thread talking about framebuffer drivers? One problem you _may_
be hitting is the configuration of both framebuffers re. resolution and
color depth. I seem to remember there were some problems in that area...
But I can't remember anything specific.

Sorry for not beeing of more help..
