intel_extreme: invalid mode set!

[Sintendo]

Haiku fails to set up a 1024x600 resolution on my Acer Aspire One A150 and instead stays in 800x600, showing nothing but a 1 pixel high bar at the top of the screen, just as described in #7441 and #8132.

While booting it fails setting up the proper resolution three times:

...

Last message repeated 1 time

KERN: intel_get_mode_info()
KERN: intel_set_display_mode(1024x600)

KERN: PLL limits, max: p 80 (p1 8, p2 5), n 10, m 120 (m1 22, m2 11)
KERN: intel_get_frame_buffer_config()
...

By looking at the changes made to the intel_extreme driver and testing older nightly builds, I've found that the regression was caused after hrev42719 (works) and before hrev42751 (fails). I haven't been able to test the builds in between, but hrev42741 is probably the culprit.

Should be fixed with hrev45352.
