Oh well, so much for that theory then. ;-)

The data sheet says that you feed in basically the same command
structure as with 1wire except that there's a separate clock instead
of timing, and that you don't select the chip before talking to it.
IMHO the whole idea is somewhat flawed: as soon as you talk to it using
the 3-wire interface, it won't respond to 1wire commands any more.
There is no way to get any consistent metric of your bus quality that way.
Native 1wire seems preferable.
You could emulate the DS2404 ...
