comments on vt as console...

So, I decided to play around w/ vt after the recent UTF-8 discussion,
and noticed some issues w/ it...

First, if you load the gallant font, things don't look very good...  This
is probably because of the fact that I'm using the vga driver:
VT: running with driver "vga".

and the default resolution is 640x480... The gallant font is probably
much higher res, and when I load it, the text screen size drops to
53x21, and the text is all chopped off.  This is probably due to bad
calculation on scaling...

Second, once one vty has the gallant font loaded, if you switch vty's,
it can occure that the new vty does not display ANY text..  The display
is mostly blank...

Third, w/ the other font loaded, the border doesn't always properly
get cleared...

Fourth, when switching screens, there is a brief flash of vertical
stripes before the new screen comes on...  Can we do something to make
sure that this transition is clean?  Either a completely blank screen,
or ideally, no blank screen, but the new text appearing?

$ sysctl kern.vt
