On PPC32, CONFIG_ISA is kinda hack'ish.  I know it will / must work on
PRePs, and it _may_ but I'm not certain of some CHRP machines as well.
So you can probably look at the i386 versions of the functions (save for
udelay as Ben mentioned) and do something like:
if (_machine == _MACH_prep) {
 ... do i386 version ...
} else
 return -EINVAL; // whatever
