Ya I gave this a shot and it seems like with this device model and
bios it doesn't really pass the card through at all, in that there is
no message about the expansion/option rom at boot, and once I'm into
Solaris and run scanpci, nothing shows up at all (it is at least
enumerable under traditional).  There isn't a lot of logging to
indicate a problem either, here is the qemu-dm-solaris.log:

xc: error: linux_gnttab_set_max_grants: ioctl SET_MAX_GRANTS failed
(22 = Invalid argument): Internal error
xen be: qdisk-768: xc_gnttab_set_max_grants failed: Invalid argument
xc: error: linux_gnttab_set_max_grants: ioctl SET_MAX_GRANTS failed
(22 = Invalid argument): Internal error
xen be: qdisk-5632: xc_gnttab_set_max_grants failed: Invalid argument
xen be: qdisk-768: error: unknown operation (3)

xen-hotplug.log prints a couple of the following lines, but it also
prints them for traditional:
RTNETLINK answers: Operation not supported

xl pci-list thinks it has attached it:
derickso@xen:/var/log/xen$ sudo xl pci-list solaris
Vdev Device
00.0 0000:02:00.0

I've also attached the xl dmesg from both a rombios and seabios boot
if that is helpful.

Thanks,
David
