   I think either of these might work:

append="com2=57600,8n1 console=com2 sched=credit dom0_mem=1024M -- nomca
nosmp console=tty0 console=ttyS0 root=/dev/sda3"

append="com2=57600,8n1 console=com2 sched=credit dom0_mem=1024M -- nomca
nosmp console=tty0 xencons=ttyS1 console=ttyS1 root=/dev/sda3"

The default xencons device for dom0 is ttyS0 and the dom0 kernel no
longer enumerates the serial ports on it's own.  Note you'll need to run
a getty on ttyS0.  Do these work?  Thanks,

        Alex
