Agreed. At the same time, I believe there is a class of user in between
casual consumer and developer that wants to rebuild their kernel for
whatever reasons (preemptive kernel or Core2, that kind of thing) that
this will affect.

One solution is for the dkms_autoinstaller script to *always* build for
any given combination. If that doesn't appeal, when building maybe save
an md5sum of /lib/modules/$kernel/modules.symbols (produced by depmod)
to /var/lib/dkms/$module_in_tree/$version_in_tree/$kernel, and compare
it when getting 'dkms status ...'?  --- Admittedly, that's just off the
top of my head. Not at all sure that would work...

Peter
