I rather doubt that the POH says anything about taxiing on one engine.

There is quite a bit of info about single engine performances
though. Nothing specific about taxiing with one engine I
must admit, but there are a lot of other things that are
omitted as well, for instance, take off performances
with the wings off, that sort of things.

As for training/rating; a lot of the training involves doing
things with an engine off (well, simulated engine failure,
or really switching it off depending on how adventurous the
instructor is and/or how close you are of a really big runway,
which we have around here -- I had plenty of fun at A****er);
Landing on one engine is something I have done a few times,
actually everytime you seat with an instructor (MEI), a
designated examiner (and in my case, I *also* did a 'medical
flight test' with a FAA inspector to upgrade my medical and
we picked the twin because it is more fun), they are all very
keen on messing with the engine controls :-), and just for
kicks we included taxiing out of the runway; with some
momentum, no problem -- I mean, you can get out of the runway
and wait for someone to tow you out of your misery without
getting in anyone's way; With some momentum, I can taxi out
of the runway with a glider for that matter. But once stopped,
or sufficiently slowed down, I guarantee you that you
won't go anywhere without pushing or towing it (in the
conventional light twin, well in the glider too)

A flight sim that has reasonably good models is Xplane,
which you may want to check out,
