>Description:

With two old VGA cards (a "Diamond Stealth" from 1989, and an unknown
card with a trident tvga9000 chipset), the vt driver probes the card
as "ega", and never actually outputs anything.  Other than that, the
machine is happy; I can use a serial tty and the network with no
problem.

The pc driver works ok. It probes the device as "mono", but at least
it outputs stuff.

If you want me to instrument pcvt_sup.c:vga_test, say so.
