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:
{{{

}}}
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.
