Well, technically it's compiled as a module and installed using the 
normal module tools.  The problem is that particular PCI card is 
proprietary and so is the code so it's not something that can be 
released to the public.


(Most of the public doesn't have this particular card, either.  At $20k 
a pop, there aren't many of them).
