Is it not writing to /var/log/dmesg|syslog|messages?

Here is some more patches for the hvc stuff that are relatively recent:

It does a switch over to the other console.
I would expect xm dmesg to give the xen messages and dmesg to give the
dom0 messages. Could you be losing it when sending it to the serial console?

Adding the hvc console worked for me, if I recall correctly. We should add that
to the wiki as well (if it isn't there already).
