I've been looking at doing a driver for ESS1868/69/78/79 since these
cards/chipsets are resonably similar. Unfortunately I'm sort of overloaded
at work now so I never got further than deciding that you can borrow a lot
of code from the ESS1688 driver and that there are three ways of detecting
the cards. 1. PNP detection via PNP-driver (One has to get hold of the
various PNP-id:s these cards use) 2. Detecting an already configured card
like the ES1688 driver. (Although not exactly the way that driver does
it) 3. Manually doing the PNP-config as instructed in the docs (the docs
gives some reasons for why the computer manufacturer should avoid PNP)
(quite a lot of work).
