dmesg of the guest booting both with and without the pci device might be
interesting. So would the output of "xl -vvv create" in both cases.

Is the 512MB number coming only from within the guest or is it also
visible in e.g. xl list? You could try ballooning up inside the guest,
by writing to the /sys/devices/system/xen_memory/xen_memory0/target_kb
sysfs node.

Lastly you should try a more recent domU kernel.
