	Stock 3.0-RELEASE.  VESA and VM86 options in compiled into kernel.

        VESA: v1.2, 4096k memory, flags:0x1, mode table:0xf00c4c64 (c0004c64)
        VESA: STB Velocity 3D (S3 86C988)
        sc0 at 0x60-0x6f irq 1 on motherboard
        sc0: VGA color <16 virtual consoles, flags=0x0>

>Description:

	I like the new VESA support!  However, if I'm not careful I can
	lock my system pretty easily.  For example, switch ttyv0 to
	132x43, then Alt-F2 over to ttyv1.  Instant lock.  If I switch
	all the ttys over to the same mode before a tty switch (via 
	vidcontrol < /dev/ttyv1 132x40, etc.) then tty switches seem
	to work OK.  However if I try to switch ttyv0 back to 80x60 while
	ttyv0 is active, I hit another lock up.

	BTW, I'd sure like to do 132x60 on my 21" but it says 
	"not supported" (though that's what it says when you haven't loaded 
	the right font.  I've loaded an 8x8 font and can do 80x60.  Any 
	tricks to getting this to work?

>How-To-Repeat:

	Alt-F1
	vidcontrol 132x60
	Alt-F2

>Fix:
	
	Unknown.

	--Thanks.
