There is only com1 in Xen from what I can see,

There is a com2 as well, so you should be able to do com2=stuff just like
with com1.

I've no idea what console=com1,com2 will do though I'm afraid, but it'd be
interesting to try for sure.

I also think it odd that dom0 doesn't see ttyS1 when Xen isn't using it,
I'd have thought only the one Xen was actually using would be invisible,
but maybe ttyS0 being missing causes it to never look for ttyS1 or
I was always under the impression that IPMI based stuff (including serial consoles) required the OS to have IPMI drivers (I may of course be completely wrong about this though), IPMI is detected at a low level, so dom0 may not be seeing that anything related to it is even there to set up.
