I finally got a chance over the weekend to try out the current DRI
code on my new 8500 card and compare it with the offering from ATI.
The following is a cheers & jeers style review. Hopefully someone
will find it helpful.
My setup: 950MHz Athlon (early/pre-thunderbird), KT133 motherboard,

Perfect. Thanks.
You also don't exhibit a texture border bug that the ATI drivers

Looks very interesting, is there a chance for a Linux/PPC build?
