Define "everything" Obviously, not everything suffers from this
problem. In fact, lacking proof otherwise, I would tend to believe that
this is a niche problem.

This is the first time I have seen this phenomena occur. A warning when
the drive starts, or should I say tries to start, that there is a
mismatch would have been nice. I was not aware that the driver had been
rebuild and therefore wasted valuable time tracking down the problem.
Even the warning that I received when manually attempting to load the
driver was not displayed when booting up, unless it flew past the
screen faster than I could view it, nor was it listed in the system
log. The Xorg log simply stated it couldn't load the module, which is
in itself a start. I am assuming that if the module cannot give a proper
reason for its failure to load then the Xorg log really has nothing to
log. That is just an unproven assumption though.
