This is just a "terminology issue": The fonts displayed in
the 80x25 (I think it's really 25 lines, not 24) are stored
in the graphics card, whereas the VGA-based console uses fonts
supplied and graphics generated by the OS, which are of course
a raster representation. The graphics card can also generate
characters for alternate fonts, but as far as I understand,
those fonts are "stored" in the card and only selected by the
OS, so you can't display characters that the card does not
have in its memory - of course it stores its characters in
a raster format as well.

I hope I didn't say something stupid. ;-)

I think FreeBSD 9 will do, whereas FreeBSD 10.1 will probably
have the new environment by default...
