3dlabs has closed drivers available for various Oxygen and Wildcat based cards at: http://www.3dlabs.com/support/drivers/ The Wildcat driver is DRI-based. Source is provided for the DRM component but under a scary-looking license header. The userspace components are only provided as binary blobs. There may or may not be a linux Oxygen driver, their download page lists eight Oxygen cards and six distributions, and I haven't had the patience to try all the combinations. To the best of my knowledge, no one has approached 3dlabs about opening these drivers.
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
