asr cannot work on big-endian machines, nor can it work on machines
with a 64-bit address space.  So that limits it to i386 without PAE.
There is nothing stopping it from working with other arches, but it
needs to be made busdma-aware for starters,  I started on this last
spring but was asked to stop for other reasons.  Maybe it will happen
for 5.4, dunno.
