Hmm, if I were you, I'd require that your driver at least saw the dos
driver at build time (ie build a util to take the code/data/... from the
dos driver, build the linux driver with that),

Alternitavly write a userspace initaliser that does the same. Like the
Ensoniq SoundScape sound card has a ssinit.exe (supplied by Ensoniq), and
a linux ssinit (third party) that operates through the sound driver to
initalise the card (uploades microcode to the card). It's easier in this
case as the microcode is seperate already. Also either built with the
code/data/... from the dos driver, or if the extraction code is small
enough, do it on the fly ....

You'll have to make sure that you always get the right code tho, you can't
assume it won't change (in newer versions), and you can't assume that
it'll stay at a static ofset (in newer versions). You proberbly can
assume that it's not going to change size (tho ...).

Well init the card with this util before you use it, you need to have the
dos driver about as well btw isn't that hard ...
