VBE

[Jan Fricke]

Hallo!
While testing the VBE functions of "grub" I thought may be one
can do more than only rotate colors. So I changed the function
"testvbe" to a function "tetris" which has to be called with
an 8 bpp VBE mode. If you think it is funny enough to added
to "grub" I will make a "proper" diff, i.e. comment everything,
use nicer variable names, write "ChangeLog" entry...

To Okuji: Please tell me, whether you need more debug runs for
function "ioprobe".

Best wishes                              Jan
