Not sure who "we" is in this context.

Especially dropping easy support for all smbus devices (which are often like
 this) would seem quite wrong to me. And for real ISA devices there tends to 
be a surprisingly large user base left for those.

The config option Ingo proposed is a good idea though.

Or they can just use 64bit which never defines CONFIG_ISA, but of course
still has to support all the similar smbus drivers.
