Jean, this may be totally unrelated, but I recently read something about the 
different way 2.6.20 kernels use modules causing some problems with 
older-type pci boards.  I don't remember the details, but I do remember 
thinking an 'ouch' and wondering if it would affect my DV10+.  It sounded as 
though it would.

If you haven't tried it already, could you install a 2.6.19 kernel and see if 
that cures the problem?
