I was looking through the the databooks regarding PCI gart and I noticed that r128, radeon, and r200 all do PCI gart the same way. that said, I also noticed that PCI GART is limited to 4 MB of system memory when used with a PCI card and 32 MB when used with an AGP card. I haven't yet looked at the gart code in the radeon driver, but perhaps it is trying to use more than 4 MB of system memory and that is causing the slow down. it may also explain why PCI gart seems to "work" on AGP cards and older radeons, but not on newer PCI ones. On the other hand perhaps the driver already takes care of this... I haven't checked.
