setfont seems to work fine, I tried Georgian-Fixed16 (256 chars) and
Uni2-VGA16 (512 chars) under /usr/share/consolefonts/ in my Ubuntu box,
including setting all consoles to the same font:

for i in {1..6}; do
        sudo setfont -C /dev/tty${i} /usr/share/consolefonts/Georgian-Fixed16.psf.gz
done

Font rotation also seems to work fine:

for i in {1..4}; do
        echo $i | sudo tee /sys/class/graphics/fbcon/rotate
        sleep 1
done

One last thing I can think of is tile blitting, but I don't have the
hardware (e.g. a Matrox G400 card, see FB_TILEBLITTING in
drivers/video/fbdev/Kconfig) at hand, nor did I figure out how to
simulate it after searching for a while.  However based on the other
tests above I believe vc->vc_font.charcount is set properly.

Thanks,
Peilin Ye
