kdrive:
Driver in a day. I took the r128 driver from andersca and tried to make a SiS 300-series driver for kdrive. I'm close I feel, but nothing's being rendered yet. I got frustrated, so I decided to try a Radeon driver. Surprise, it was really easy, and taking code from XFree86 I got it working within a few hours. Then I noticed that Rage 128's 2d acceleration was very, very similar to that of the Radeon, so I added Rage 128 support to it. Now we've got an "ati" accelerated kdrive driver that supports both. It's got some limitations (broken at non-16-bit, like the previous r128 driver, and lacks all but two Rage 128 PCI IDs), but I'm pretty satisfied.
