Re: Call for Testing: UEFI Changes

Confirmed both loader (with boot1) part and efirt.ko part.
Working OK on my ThinkPad420 (with nvidia GPU) at r331864.

No benefit (VGA resolution) but no new harm (no panic nor silent
reboot).

 *Maybe gracefully falling back to mode 0.

As I'm on x11/nvidia-driver, completely no test is done with
drm-next.

One more to mention.
I've cherry-picked r330868, r331241 and r331361 on stable/11 after
r331114, amd64 and works OK as on head.
Additional cherry-picking of r331365 is OK, too.

Without r330868, my ThinkPad silently reboots within about 10-60
minutes range, maybe by actual access to UEFI RS.
With r331241 without r331361 causes instant panic on loading efirt.ko.
So all 3 (4) revs should be MFC'ed together.

Sorry for delay.
