The "vga" support is actually VGA-specific. There is also EGA support
and a more generic "pcdisplay" for CGA and monochrome. Switching to
pcdisplay might save a bit of space. Switching to the low-featured
"pc0" display driver instead of wsdisplay will also save a bunch of
space (but you lose support for things like virtual terminals).
