Well, "much of a problem" is relative.  I was once on a consluting gig
where we had to hack on the driver for the Ethernet chip in use because
of endianness issues.  (I wasn't doing that part, so I don't know how
much of a mess it was to do.  I glanced over the result and it looked
fairly extensive, but all that means, really, is that they were
textually scattered.)

There are probably fairly few drivers with problems.  If you don't want
to use any of them, it's no problem at all; if you do, it's a pain.  In
the Grand NetBSD Scheme Of Things, Jason is probably right, it's not
much of a problem - but for an individual situation, it can be a PITA.
