4. XF86Config options recognized and used by Rendition driver

Option "sw_cursor"

Disables use of the hardware cursor.

Option "overclock_mem"

Run the memory at a higher clock. Useful on some cards with display glitches at higher resolutions. But adds the risk to damage the hardware. Use with caution.

DacSpeed "MHz"

Set custom ramdac limit. We have currently no way of knowing if the v2x00 chip is a v2100 (170MHz) or v2200 (203MHz and 230MHz) so we assume the lowest. Use this option to manualy override the value.
