Sorry for the delay.

Setting UseXVidMode to "N" will not help in this case I'm afraid. Disabling it
will not affect gamma ramp, code in xvidmode.c specifically mentions that

/* In desktop mode, do not switch resolution... But still use the Gamma ramp
stuff */

if usexvidmode is set to false. (I tested this too)
(dlls/winex11.drv/xvidmode.c near line 172)

I assume key in question is

HKCU\Software\Wine\AppDefaults\app.exe\X11Driver\UseXVidMode
