	FWIW, I have a TI Extensa 565CD, with a Cirrus 7543 PCI video
board. 'SuperProbe' complains that

	Chipset: Cirrus (chipset unknown)
		Signature data: 30 (please report)
	Memory:  512 Kbytes
	RAMDAC:  Sierra SC1148{2,3,4} 15-bit or SC1148{5,7,9} 15/16-bit HiColor
		 (with 6-bit wide lookup tables (or in 6-bit mode))

I've gotten XFree86 to work in 640x480x256 SVGA mode with the following
device definition in XF86Config:

	Section "Device"
		Identifier	"Cirrus Logic 7543 PCI"
		VendorName	"Cirrus"
		BoardName	"7543 PCI"
		VideoRam	1024
		Chipset		"clgd6235"	# But seems to accept most
						# other Cirrus chipsets
	EndSection
