Interesting. On my stable/9 desktop with i915kms I can't reproduce
this; after switching back to X the previous display is restored, and
then a redraw happens, within a few hundred mS. I do see it on my
laptop, which also has i915kms but newer software (recent CURRENT, and
newer xorg packages). I'll see if I can gather more information at
BSDCan next week.

Can you describe the corruption in some more detail, or share a
picture of it? I haven't observed something like this with stock vt,
and the vt_vga driver.

This isn't currently planned, but I'll keep it in mind if I look into
future work on the keyboard input path.

I've been using vt for about six months and am now used to the default
vt font -- the VGA ROM font looks odd to me now. However, I believe
the primary motivation behind the font choice was the glyph coverage.
I now have a vt-compatible version of the VGA ROM font, but it only
has about half of the characters.
