I'd just hack it by a) renaming the modules or b) rm them.
But I guess you are looking for a proper solution.
If you have a working kernel version and a more recent non-working one,
then did you check the bug tracking, did you see if this is a known
issue, maybe file a bug against the newer kernel? Or maybe this distro
has a particular way to blacklist?
