Well, actually I also thought about that. Here is why I didn't try:  
Apple's kernel driver interface (IOKit) is really big. One would have  
to do an IOKit port to Linux. Ok, it is open source, so that would be  
possible. But I estimated doing that pciproxy hack would be simpler  
and faster to do than porting the whole IOKit. I guess the Win32  
driver interface is not so big and you don't have access to each and  
everything from your driver as it is the case with OS X aka. Darwin.

However, if there are some other guys willing to tackle that IOKit  
porting idea, I'll be happy to join ;-)

thanks :-)
