GENERIC.MPACPI with enabling "vga0 at isa?" boots normally.

isa0 at pcib0
vga0 at isa0 port 0x3b0-0x3df iomem 0xa0000-0xbffff
wsdisplay0 at vga0 kbdmux 1: console (80x25, vt100 emulation), using wskbd0
wsmux1: connecting to wsdisplay0

>How-To-Repeat:
Boot the GENERIC.MPACPI kernel.

>Fix:
Removing the line "no vga0 at isa?" from sys/arch/i386/conf/GENERIC.MPACPI fixes the problem.
