A little progress update. With the patch in this message:

http://lists.xensource.com/archives/html/xen-devel/2005-12/msg00491.html

I can move xencons to use any reasonable ttyX or ttySX value. On my xen0 domain, I can add "xencons=ttyS8 console=ttyS8" which skips me over the range of ttyS devices claimed by the 8250 serial driver (I'm leaving out CONFIG_SERIAL_8250_ACPI to prevent having both xen and dom0 claim my serial console UART, leaving the PCI UARTs). Furthermore, I can boot domU with the same trick, skipping over the 8250 claimed ports and avoiding the conflict with CONFIG_VT.

I guess maybe it's time to hide the serial console UART from dom0. I'd really prefer some way that the hypervisor could do it automagically, but I guess I'll settle for a boot time option.
