Hi Bengt,

Indeed! And this works. With 'nooptions VESA' and syscons I can
suspend/resume from X. The image turns dotty and to low color mode for
a moment, but it recovers immediately. X log:

[   113.387] (II) AIGLX: Suspending AIGLX clients for VT switch
[   113.387] (WW) intel(0): drmDropMaster failed: Unknown error: -22
[   120.957] (II) AIGLX: Resuming AIGLX clients after VT switch
[   120.958] (II) intel(0): EDID vendor "CMN", prod id 5239
[   120.958] (II) intel(0): Printing DDC gathered Modelines:

1439 1512  768 771 775 789 -hsync -vsync (47.3 kHz eP)

So, the retry hack is needed only with vt.
