- Split core DRM routines back into their own module, rather than using the nasty templated system like before. - Development-class R300 support in radeon driver (requires userland pieces, of course). - Mach64 driver (haven't tested in a while -- my mach64s no longer fit in the testbox). Covers Rage Pros, Rage Mobility P/M, Rage XL, and some others. - i915 driver files, which just need to get drm_drv.c fixed to allow attachment to the drmsub device. Covers i830 through i915 integrated graphics. - savage driver files, which should require minimal changes to work. Covers the Savage3D, Savage IX/MX, Savage 4, ProSavage. - Support for color and texture tiling and HyperZ features of Radeon. Thanks to: scottl (much p4 handholding) Jung-uk Kim (helpful prodding) PR: [1] kern/76879, [2] kern/72548 Submitted by: [1] Alex, lesha at intercaf dot ru [2] Shaun Jurrens, shaun at shamz dot net
