That's a reasonable approach, and it isn't too difficult either -
somebody motivated enough could do a patch...

Hmm, I think I have a question and a suggestion here: what is it you
have problem with minstrel ? I don't care which one but both works
well enough here. Maybe you need that sorted instead.

The other thing is, you can probably patch compat-wireless to do
something similiar or at least experiment with it, as long as your
kernel is configured with most of them as modules. Switching
compat-wireless is quite easy, and particularly with the
'driver-select rtl818x' option you just rebuild about 6 kernel modules
instead of the usual 50+, which makes it quite quick and painless.
