[intel] 1080p at 60Hz on an intel G45 chipset

[strawks]

Hi all,

I have a G45 chipset working fine at 1080p at 50Hz but i can't get it to 
work at 60Hz.

The X says :
Not using mode "1080p at 60" (mode clock too high)

My modeline is defined as follow (obtained with cvt -vr 1920 1080 60) :
ModeLine "1080p at 60" 173.00 1920 2048 2248 2576 1080 1083 1088 1120

I don't really need it but just curious if I missed something (maybe a 
bad modeline for this card?) or is it just not supported by the driver 
(the chipset does support 1080p at 60Hz, win32 uses this mode by default, 
as reported by my TV).
