I don't want to get hopes up prematurely, but we think we might be able to emulate enough of the newconfig-style interface via the same sort of wrapper shims that we use for the old isa and pci drivers. If that works out, then it should make porting/using a NetBSD/OpenBSD/BSDI driver a lot easier. There's bound to be #ifdefs required no matter what, but it shouldn't require two totally different config interfaces. Of course, this is still a "might" case since it hasn't been written. However, it would be quite hard to get this to work seamlessly for sub-busses and devices, eg: PCIC->PCCARD->CARDBUS->etc. Simple devices shouldn't be too hard though, but even then there are seriously non-trivial differences in the tty, block/character devices, VM, networking, etc. Even if the config interface was compatable it wouldn't ever be a 'drop in' option, even with 'newconfig'.
