Changes done for each driverversion:

via_driver (SVN 0.16, Rudolf)

• Initial setup based on nVidia driver 0.30;
• Kerneldriver uses MTR-WC mapping where available;
• Accelerant uses AGP busmanager to enable AGP FW where available;
• Added hardware cursor;
• Added RAM size autodetection, as preset by the system BIOS;
• Added support for virtualscreens (CRTC startadress and memory pitch programming);
• Added CRTC1 timing programming and updated constraints, including GET_TIMING_CONSTRAINTS hook;
• Added mode colordepth programming;
• Added CRTC FIFO fetch limit programming (seems specific to VIA);
• Added colorpalette programming;
• Added DPMS support;
• Added primary head pixelPLL programming (refreshrate is now set);
• Added switch to 'enhanced mode' making the driver independant from a preset VESA mode;
• Added video overlay support;
• Finalized virtualscreen panning granularity constraints programming.

Still todo:

• 2D acceleration;
• And yet more could be done.
