As these bugs might also be present on other chips (most likely they are!) some comments: Bug #4312 Most important is CRTC register 2f, signal quality is also improved for higher vclk values by changing set_vclk() according to the X drivers and cyblafb.c bug # 4386 Acceleration is broken for all BLADE 3D chips for all versions of kernel 2.6 except for 32bit modes. Most important reason is that the u32 col parameter of the graphics engine needs the color value replicated to all u8 of the u32 (8bit modes) and to both u16 of the u32. cu, Knut ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
