We've already got a little bit of one-wire bus support in sys/dev/ic/ds.h,
which is used by sys/arch/acorn26/ioc/ssn.c and by something in
sys/arch/amiga. Making it more general might well be useful, and ISTR that
the acorn26 implementation never worked properly anyway. If it had, I would
have ported it to NetBSD/acorn32 so that we could get the system Ethernet
address on acorn32 systems without help from RISC OS.
Or, in summary, yes please!
