I wondered that as well. For both the i386 and alpha port
the definitions end up in /usr/include/machine/bus.h and
stripping off the arch-specific prefix shows that their value
is the same. In fact they appear to be the only #define in
bus.h with the arch-specific prefix besides the multiple-inclusion
#defines. I think they could be combined, but defer the
decision (commit) to the folks working on the new bus code
as they know their way around this code much better than I
do.
