Ok, so your system is fully AGP v3 compliant, (both host and gfx card).
The missing check highlighted in your diff means that we only do
AGPv3 stuff if we have an AGP 3.5 host bridge. You have a 3.0 bridge,
so it was falling back to AGP v2. My suspicion now is that the 648 and
746 chipsets vary too much for them to both use the generic routines,
so I'll reinstate the check. It'll still report that it finds an
AGP v3.0 device, but until someone comes forward with chipset docs,
it looks like it'll be limited to AGP v2. (I'm amazed that it works
at all, really).
It survives a testgart run too ?
