I'm not convinced the patches attached above are the correct approach for
this.  The only safe way to determine wether a card is actually AGP or not,
is to walk the PCI extended capabilities list.  I wrote a patch for the
Radeon driver a couple of years ago which does just that, which is present
in Xorg 6.7.0 and later releases.  My code was initially just a Radeon driver
specific temporary implementation, but the code has been copied aparently
into the SiS or some other driver (I don't recall which).

Ideally, the code should be factored into os-support somewhere, and all
drivers modified to use the genericized code instead of cut and pasting
it everywhere.

Initially I would have placed the code X server side, but perhaps it fits
better in kernel land?

Any thoughts?
