Agreed. When the kernel controls hardware, you can always know
the state it is in (see below).

OK, so we are confronted with (loads of?) broken hardware outthere.
We can't just ignore it, so we'll have to think up a solution to
this problem.

If GGI is a solution, why not use it (as a config option of course,
it will eat to much memory on a 386sx/4mb used as a router).
It might not be stable enough for mainstream use, so we could flag
it with CONFIG_EXPERIMENTAL instead...

I for one would be interested in at least testing GGI (even though
I don't have 'broken HW'...
