See the ep driver ... The NetBSD autoconfiguration scheme allows for 
"devices" with "attachments".  The aic7xxx "driver" is called "ahc".  For 
"ahc" devices that attach to pci, we have "ahc_pci" ... This is somewhat 
intuitive, and has the pleasant side-effect of not tying ones self down 
to a model number, which might change in the future.  If we were to name 
the ep driver as you suggest, we'd have:

	dev/isa/3c509.c
	dev/eisa/3c579.c
	dev/pci/3c590.c

BUT!  the 3c595 is handled by the PCI front-end ... and 3c509 cards that 
masquerade as EISA are handled by the EISA front-end.  I like 
"<driver>_<bus>" a lot better :-)

Another way to look at it: Why diverge from NetBSD's naming scheme just 
because another OS happens to name the files differently?  :-)
