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:
