in my case from December: no fix found till now.
Upgraded my Gentoo to app-emulation/xen-tools-4.2.1-r1, 
app-emulation/xen-4.2.1-r2.
A workaround is to boot the domU without the PCI-Device in config and 
pass it later on. This way you can work with all the RAM you need 
_and_ the PCI-Device.
Still hoping for a solution in one of the next updates.

When I shutdown this domU for reboot I keep a 'ghost' in xl list

xen xen # xl list
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0  7529     4     r-----      85.2
colin                                        1  2048     3     -b----     102.3
(null)                                       2     6     2     --ps-d     144.6

which can be removed by killing the corresponding qemu-system-i386 process.

Regards,
Christian
