I actually wouldn't worry. We've got lots of other drivers that don't
work on all the platforms they should because nobody has ever tried them
out.

At least if they compile on the different platforms people will be able
to try them. It's not making anything any worse - it used to not work and
it still doesn't work is the failure case 8)
