Subject: VGA hell

 manpages are vga(3), vgadb(6), vga(8), plan9.ini(8)

 to dump the registers, and see if your card is in /lib/vgadb:
	aux/vga -p > /tmp/x
 if that doesn't kill the system, use the following for more info:
	aux/vga -pv > /tmp/xx
 what does this do?:
	aux/vga -lpv
 Force the VGA controller to a known state: 
	aux/vga -m vga -l
 Getting more fancy:
	aux/vga -m multisync75 -l 1024x768x8
	aux/vga -m multisync75 -l 1280x1024x8
 to find the current settings:
	cat /dev/vgactl
