I have the specs for this monster, but it's a bit funky.
For one it uses MMIO instead of PCI config space for most things.
It can also be configured as a single level or 2-level GART which
isn't like any that we currently support. (In fact the agpgart code
really doesn't handle this concept at all due to the extensive usage
of aperture type macros/typedefs).
I need to set aside some time to get it finished off sometime, but it's
no small amount of work.
I already have a bare-bones driver that just probes the aperture size
etc, just need to come up with a way of supporting both aperture types.
