One thing I've planed to do is rewrite text mode rendering.  There are
some helpers for that in ui/qemu-pixman.c.  They are used by the qemu
text console today (i.e. "-chardev vc" + Ctrl-Alt-$nr console switching,
see ui/console.c).  In theory these helpers should work as-is for vga
text mode rendering too, allowing to zap a whole bunch of glyph drawing
code from vga.c.

Not sure how low hanging that actually is though ...
