The following Section "Device" options are supported by the MGA driver:
Option "sw_cursor"
Will disable the hardware cursor on the Millennium and Millennium II.
Option "no_accel"
Will disable all hardware acceleration (oh my!).
Option "no_pixmap_cache"
Will disable caching of pixmaps in offscreen video ram.
Option "sync_on_green"
Will enable syncing on green (currently broken for Mystique).
Option "pci_retry"
This will allow the MGA hardware to generate a pci_disconnect based on accelerator FIFO status. This can yield large performance boosts for some graphics operations but has a tendency to hog the PCI bus so it is turned off by default.
as appropriate so that the server doesn't have to probe for it.
