915resolution enhancements

[Vandrus Zoltán]

Hi, 

915resolution didn't worked on my intel card out of the box, but with a
couple of trivial lines and with the help of the patch from here
(http://www.insanelymac.com/forum/lofiversion/index.php/t129744.html)
it was really easy to make it work, and those lines really don't do
anything, just let 915resolution recognize my chipset and do what it
does for the others. I already filed a bug report with the attached
patch: (http://savannah.gnu.org/bugs/?33770).

Another nice feature was to give an ability to 915resolution to suppress
its messages if everything works. Bug report:

Although i think you don't really have time for such minor cosmetic
things, and i think my patch is really ugly, it was a thing only for me,
and I'm rather clueless how are these things made in other programs.

Btw, i really like what you did, i could even managed to boot with a
totally messed up config using the built-in shell, I think having that
much control and robustness right at the start is awesome.
