I just installed OpenSuSE 10.2 GM on the T42p laptop I'm using, keeping my old
homedir.

If I leave the laptop alone for a while, the backlight strength will change in
an erratic fashion. Sometimes it will dim successfully, other times it will dim
and then immediately be set back to high strength, and yet other times it will
get into a state where it flickers very quickly between dimmed and high
strength. The flickering will stop after I interact with the laptop for a while
(but not immediately).

When this happens, the backlight strengh centered mini-window will show up, and
it will remain for as long as the flickering goes on. The CPU consumption will
be at 100%, and this also ceases along with the flickering.

I managed to get some 'top' output during flickering:
