>Description:
	
	When booting with the configuration as shown below, the wscons
	console is unusable.  By this I mean that moderate activity on
	the console causes random junk to appear. This happens when
	switching virtual consoles for instance. When halting back into
	the SRM, the display remains in a weird state, apparently unable
	to scroll, or somesuch.

	Heavy use, such as cat INSTALL.more, can cause spontaneous
	reboots. This is at least repeatable with the installation
	kernel.

	I suspect this is related to the Pyxis with DMA bug in my
	machine, but I have not discovered the use of DMA yet in my
	cursory inspection of the wscons code.

	By default, the SRM refuses to boot with the card inserted, and
	must be pacified with a 
	>>> set pci_device_override 88c15333
	for the machine to boot at all.

	I also tried this with a -current kernel, freshly supped, and
	the problem persists.

>Fix:
	
	workaround: ignore existence of video card, or even remove it.
	Use serial console instead. This is obviously far from
	satisfactory.
