I am on 9.10 Karmic and can use the brightness keys just fine without
system lockups.  I am also using a 4810TZ with i915 kernel drive for:

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series
Chipset Integrated Graphics Controller (rev 07)

My System BIOS is v1.15 and VGA BIOS is version 1736 which I think is
what it came with.
