Is there a plan to add a config entry for ATHEROS_AR231X (or did
I miss it?)  Someone will one day run their Kconfig checker and
report it missing.

I like this better, but there probably needs to be a mutual
exclusion so that randconfig builds don't break.  Then you don't
get to build both still, but the resulting Makefile is a bit more
normal.  And then if someone shows up saying that they really do
have some AR231X device with PCI, then it's more obvious what they
need to do to fix it (i.e. separate bus interfaces from core).

Something like?
select ATH5K_PCI if (PCI && !ATHEROS_AR231X)
or
depends on ((PCI && !ATHEROS_AR231X) || (!PCI && ATHEROS_AR231X)) ...
