gamma settings don't work

[Dmitry Baryshev]

Hello guys.

I have a problem with setting gamma in X 1.4.2 in Debian. Xgamma
doesn't report any problem, but it also doesn't apply gamma settings.
XF86VidModeSetGamma() function also returns "False". I use
self-compiled via driver on that system (for cx700 video chip from
VIA). On my own system with the same Debian, X version and nVidia card
gamma works fine.

Any ideas? Is it a driver issue? Thanks.
