915resolution isn't needed with xf86-video-intel 2.0, because this
version doesn't use the bios for modesetting.  However, it seems that
the driver doesn't detect the correct mode in your case.
What kind of machine is that (laptop/desktop/...), and what kind of
monitor (laptop panel/vga/dvi/...)?

Thanks for providing them!

It might be helpful to report this bug upstream at bugs.freedesktop.org,
Product "xorg", Component "driver/intel" (make sure to attach your
config and log there too).  Let us know it you do that.

Thanks for your report!
Cheers,
Julien
