I'm very much indebted to Daryll for his - * work on the X server. - * - * Voodoo3 support was contributed Harold Oga. Lots of additions - * (proper acceleration, 24 bpp, hardware cursor) and bug fixes by Attila - * Kesmarki. Thanks guys! - * - * Voodoo1 and Voodoo2 support aren't relevant to this driver as they - * behave very differently from the Voodoo3/4/5. For anyone wanting to - * use frame buffer on the Voodoo1/2, see the sstfb driver (which is - * located at http://www.sourceforge.net/projects/sstfb). - * - * While I _am_ grateful to 3Dfx for releasing the specs for Banshee, - * I do wish the next version is a bit more complete. Without the XF86 - * patches I couldn't have gotten even this far... for instance, the - * extensions to the VGA register set go completely unmentioned in the - * spec! Also, lots of references are made to the 'SST core', but no - * spec is publicly available, AFAIK. - * - * The structure of this driver comes pretty much from the Permedia - * driver by Ilario Nardinocchi, which in turn is based on skeletonfb. - * - * TODO: - * - support for 16/32 bpp needs fixing (funky bootup penguin) - * - multihead support (basically need to support an array of fb_infos) - * - support other architectures (PPC, Alpha);
