Ivo, you could look at Orinoco or Libertas. Both WLAN drivers 
support a multitude of different hardware (Libertas: CF/PCMCIA, 
SDIO, SD, USB and Orinoco: CF/PCMCIA, PCI, PPC_PMAC). And both 
have hardware abstraction layers that don't suck, obfuscate or 
create lots of duplicate code.

So AFAIK it's not the question *IF* to do hardware abstraction 
but only a question *HOW* to do it in an intelligent way. Don't 
luck at one bad implementation and disregard the whole 
concept :-)
