I do see your point, but this sorta falls in line with my point all 
along (no flame intended here), that walking through the process with 
him would have helped him understand what he was doing a little better 
for the next time.  And yes, that might have been the case with that 
driver, hence one of the things that probably would have come of 
debugging the problem rather than avoiding it would have been to backup 
the modules directory before hand.

That may be true, but we still don't know if his system was that 
wrecked.  We never got any more information beyond the OP.  After that 
it was all about reinstalling the kernel.

Again, that just proves the module was wonky, not the kernel.  Still 
doesn't mean the entire kernel needed reinstalling.

Well, I was hoping to help get him started on that NOW, rather than later.

Again, I have no reason to say that it IS mandatory for it.  I don't 
know that it was for sure.  I do think it is likely, but instead of 
trying to find out definitively, some told him how to drop a tactical 
nuke on it and thus avoid the problem altogether.
