It's what the code do.

The probe code fails in dev/ic/vga_common.c:vga_common_probe() for the
card that is not used as the primary display by the BIOS.

Well, there's only one way to use a a vga card only as a vga card : using
VGA registers. There is only one set of them. So when vga_common_probe try
to map them a second time, it fails.

Maybe there's a way to have multiple vga registers, but if there is it is
not used in NetBSD.
