80x25 mode.
XXX This doesn't handle odd modes like 80x30 on 640x480, but the driver
didn't allow that selection previously so at least it's an improvement
over the previous behaviour.
to the screen on which they are being called. The driver cannot guess
this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place. There are no functional changes
yet.
Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64.

the background. The problem was exposed when setting a non-black color
as the background, as the shift did not produce the expected fill value

apps like XFree86. Currently it supports 80x25, 80x30, 80x40 and 80x50
text modes using emulation. You can enable it by specifying `options
VGA_RASTERCONSOLE' in your kernel config file.
Note that displaying multilingual text doesn't work yet. Necessary
code is already there, but userland stuff and some functionality isn't
ready for prime time yet. I'm working on them.
