I believe chkrootkit is to blame here, the LKM check is prone to a lot of 
false positives in sid. I haven't been able to pinpoint what causes this, 
unfortunately it comes (NEW) and goes (OLD) so it's not cleaned by Tiger's 
"do not send me stuff I already know about" mechanism.

There are some know false positives in chkrookit [1] and given the way it 
checks for some of the rookits it's bound to fail sometimes, also notice 
that there are know issues with the latest kernel (2.6) and glibc (some 
processes will not show up no matter what). Also, nautilus and 
mozilla-firebird seem to cause these false positives (as reported in  
bug #222179)

It would be great if chkrootkit would detail more in the output message 
what "hidden" process leads him to believe there is a LKM so that these 
could be filtered through Tiger ignore mechanism...
