Ok, I think this should be fixed now (fixes affect fbdev target and
the linvtsw helper).

Problem was that when running on a separate VT we opened the framebuffer
before switching VTs and didn't give up the old controlling tty (on
the console the app was started from). That used to cause mode changes
and palette changes to be done to the console XGGI was started from
instead of the console that XGGI ran on, causing all sorts of weird
behaviour.

Another minor compability problem was that XGGI didn't support the
-bpp option, causing it to immediately terminate with an error message
if you used that in your xinit script. This will be fixed in XGGI 1.6.1.
