OK, narrowing it down a bit, everything seems to have gone haywire 
between kernel-2.6.8-1.524 and kernel-2.6.8-1.525.  I suspect it 
has something to do with:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=130746

but since English is my native language I'm not sure what's going on 
there but I get the sense that something's gone haywire with 
autoloading of modules and sure enough, a diff of "lsmod" between 
the 524 and 525 kernels shows there definitely a problem here:
