Unable to use intel_extreme graphics on Haswell HD4600

Description

I have a ThinkPad T440p, with only the integrated Intel HD4600 graphics. Starting with beta R3, I can only use Haiku with the safe-mode graphics driver (vesa) - with the Intel driver, I get a scrambled display.

I've tried this with R1/beta3, and hrev55504. All are booting via UEFI here.

Seems to be a dupe of #11268.

Try booting in safe-mode and adjust the Screen preferences.
Also, see #14643. I often get a black screen on bootup, but the screen comes up if I wait up to a minute...

Indeed. Merging into existing tickets.

In fail-safe mode, the only resolution option listed is 1920x1080 (correct for this laptop), 32 bits/pixel. There are lots of refresh rates listed, but only 60 Hz is valid. The workarounds listed in that ticket don't seem to help either.
