- S3 Savage driver ported. - Added support for ATI_fragment_shader registers for r200. - Improved r300 support, needed for latest r300 DRI driver. - (possibly) r300 PCIE support, needs X.Org server from CVS. - Added support for PCI Matrox cards. - Software fallbacks fixed for Rage 128, which used to render badly or hang. - Some issues reported by WITNESS are fixed. - i915 module Makefile added, as the driver may now be working, but is untested. - Added scripts for copying and preprocessing DRM CVS for inclusion in the kernel. Thanks to Daniel Stone for getting me started on that.
