I guess I was a little ambiguous. Once I got Spambayes running, I turned off 
Spamassassin. The results above were from Spambayes processing alone, and 
that after less than 24 hours of running with very minimal training. Since 
about 7 hours ago, I've gotten one additional spam in my inbox, and 97 spams 
diverted to trash - no false positives. I'm confident that performance will 
get better over the course of the week, as I train on some more mail. 

Regarding mail-lists and other filtered mail, the way Kmail works is that my 
spam filters are last in the filter chain, and most of my filters are 
configured to cease the processing of a message once it matches a filter - 
each list I belong to gets its mail filtered to its own folder, and those 
filters are configured to stop processing the message once it's filtered; in 
fact, most of my ham mail never gets to the spambayes filter - it gets 
diverted to a folder and removed from the processing chain - it makes for a 
pretty fast spam filtering setup - this wouldn't word in every scenario, but 
it works well for me.
