Gotta start somewhere ... how many of us are really out there?

I was thinking of that ... my concern, and it may be totally invalid, but
is it guaranteed to always translate the same? ie:
fxp0 at pci2:8:0: class=0x020000 card=0x10408086 chip=0x12298086 rev=0x10
vendor = 'Intel Corporation'
device = '82550/1/7/8/9 EtherExpress PRO/100(B) Ethernet Adapter'
class = network
subclass = ethernet
Will that always translate the same regardless of running 4.x vs 5.x vs
... ? If so, you are right, that does greatly simplify things ... I just
wasn't 100% certain ...
