	Cyrix GXLV + CS5530 system

>Description:
	The text mode emulation in the GXLV processor is not sufficient for
	use with the `fast scrolling' code in the vga driver.  Scrolling the
	display causes the display to be trashed in various hard-to-describe
	ways.

>How-To-Repeat:
	Boot on a GXLV system.

>Fix:
	Disable `fast scrolling' on the GXLV.
