Just missed most of this, but we do have drm_device_is_agp(dev) in the
drm, only the CVS radeon uses this at present as the DDX can tell it
also...
But on Linux it just does..
pci_find_capability(dev-pdev, PCI_CAP_ID_AGP);
which sounds like your chip says it is AGP but is connected over a PCI

I was afraid of that. :( The problem is that the MGA can *only* DMA
commands vertex data from PCI memory or AGP. In the case of the
G200 (typically only 8MB), you don't want to use 1/8th of your on-card
memory for commands either. I'll

If by address space you mean AGP aperture vs. other memory

You'll have trouble grabbing that linearly from
