Subject[PATCH] ignore vgacon if hardware not present
FromRusty Russell <>
DateThu, 29 Mar 2007 17:46:48 +1000
(Did this fall through the cracks?  I don't see it in -mm.  It's
standalone, and saves some silly code in lguest and presumably others).
==

Avoid trying to set up vgacon if there's no vga hardware present.
