I've tried Luc's driver, an old checkout still  lying about
(git SHA-ID: commit e9b86eb9b481161aaf11c2b5070435b95c8ec6bf),
and indeed, it works marvellously there, 'xgamma -gamma 0.5', 
'xgamma -gamma 1.5', ...  Nice.

But with the latest checkout
(git SHA-ID: commit 840a2d30554b8298806f8c642dd83b0ab62246be),
... xgamma probably still works, I didn't even try, because all the 
lettering got about 50% bigger, the horizontal sync dropped from 85 
to 75 Hz and made the display shift a centimetre to the right -- I 
quickly moved away from that, back to svn 249.

Tried...  X doesn't even start: it sits there, black screen, 
nonblinking cursor in the upperleft, and locked up.

One more attempt, Gonzalo, then I stop testing.  :)
