There is no i830 driver for XFree86. In my admittedly somewhat limited
understanding, the i830 drm driver is only used for dri clients. This is
apart from the 'normal' videodriver that X uses, such as the i810 driver
or the vesa driver. You can safely remove the i830 driver and still use
XFree86. You just wouldn't have dri anymore, which may cause OpenGL apps
to run slower.

No EE entries doesn't necessarily mean that the i810 driver is loaded,
but if you're happy, so am I :-)

There is 'xgamma', but it's up to the X driver to do anything usefull
with the gamma setting. For the i810, it doesn't seem to have any
effect. You do probably have some keys on the laptop to adjust the
backlight. Other than that, I wouldn't know of such a tweak.
Try finding some test image, maybe that'll give some information.
Otherwise, I'd try Windows, to see if it is a hardware thing.
