Hi Dan,
Funny, i was trying to get the same working ..doing some grub magic myself.
I now have the following:
- normal console on tty1
- serial console on hvc0
- All log output from hypervisor and kernel on both consoles
- Login on normal tty1 console
- Xen hypervisor console (3x ctrl-a still required) on the serial console

This is the grub magic i use (don't know if it's correct, but it works, so
therefore it must be ;-) )
title Xen-3.4.2-amd64 / Debian GNU/Linux, kernel
2.6.29.6-amd64-xenified-dom0
root (hd0,0)
kernel /xen-3.4.2.gz dom0_mem=768M com1=115200,8n1 console=com1,vga
module /vmlinuz-2.6.29.6 root=/dev/mapper/serveerstertje-root ro
pci=nomsi console=hvc0 console=tty1 earlyprintk=xen
module /initrd.img-2.6.29.6
And relevant part inittab:
# /sbin/getty invocations for the runlevels.
#
# The "id" field MUST be the same as the last
# characters of the device (after "tty").
#
# Format:
# <id>:<runlevels>:<action>:<process>
#
# Note that on most Debian systems tty7 is used by the X Window System,
# so if you want to add more getty's go ahead but skip tty7 if you run X.
#
1:2345:respawn:/sbin/getty 38400 tty1
2:23:respawn:/sbin/getty 38400 tty2
