I don't think does. I think that it's called by the kernel, as a response to a page fault. > > BTW, since I checked in my changes, I've been having problems with the > PCI > path again.

Doesn't make much sense to do something that is already done by the remaining kernel. Further, I don't see why the DRM should give the AGP/PCI buffers details to the X server. AFAIK this information is only used to call the DRM(dma_init), so why make it go back and forward, creating unnecessary complexity? > use the deprecated virt_to_bus.
