The only module I know about that is 'tainted' is the philips webcam
compression module pwcx, which I forced loaded with 'insmod -f'. But
unloading that didn't change the problem. Anyway the 'tainted' issue has to
do with no being in order with the GNU licence isn't it?
When I do lsmod (after reloading the pwcx module) I get:

Hmm. This machine has been working for years without any problem. I
installed more memory, but with this memory it has been running for months
now, also without problems. There are quite a number of fans in the case.

I might build a new kernel to see if that solves the problem.
<p>> As for the config file I'll check into that a bit more later.
Is the re-encoding section necessary?
