Well, maybe I understand it now :-)

I'd say this would be the developer's decision :-)
For example, the BeOS IDE driver contains code for all devices in one 
driver. I personally don't like this, and I would prefer the FreeBSD 
way of doing. But if that way would cause any disadvantages on the 
users side (i.e. manual configuration), I probably wouldn't do it.
It's also the question of how much code is shared. If there is only a 
small bunch of code necessary for every device, it might be 
unreasonably to split the driver into several ones.

Thanks :)
What drivers from yours are compatible with out license, i.e. not GPLd?
And what about that sync bug in the SiS 7018 driver? (couldn't resist 
to ask) :-)
