Yes, it will rock once it works. :)

That was about the situation a few months ago. Currently, the r128 DRI doesn't
work without AGP GART.

PCI GART support is currently being developed in a branch of the DRI CVS, but
I haven't got it to work on my Pismo yet (see the other thread about 'PPC
lockups'). As always, any help is much appreciated! :)

As for AGP GART, once PCI GART works I may have a stab at that. But I don't
expect it to give a substantial performance boost.

This is an ia32 thing and doesn't affect us.
