An UML user reported (against 2.6.13.3/UML) he got kernel Oopses when trying to rmmod (on a kernel with module unloading enabled) a module compiled with module unloading disabled. As crashing is a very correct thing to do in that case, a solution is altering the vermagic string to include this too. Possibly, however, the code should not crash in this case, even if the module didn't support unloading - it should simply abort the module removal. In this case, fixing that bug would be a better solution. I've not investigated though. (akpm: a bit marginal - root screwed up and shot himself in the foot).
