Also note that moving PnP code to the kernel does not imply that it works
any better. The kernel can do _some_ things that user processes cannot do,
but often a problem is just a problem of buggy code and/or incomplete
documentation (I'm not saying that this is the case in this particular
instance, but it has been known to happen).

And when the problem is that kind of problem, it is usually better done in
user space for rather obvious reasons. You can live with a bug in user
space, but a bug in kernel space can often be fatal.

I know some people tend to assume that by making things happen in the
kernel, they are automatically done right. I wish it was that way, and I
try to _keep_ it that way, but the way I do that is to say "no" rather
than by just hoping that things will work ;)
