Yeah, I've had it working in a couple of Linux guests, on this same
dom0, and the Solaris guest is running in PV mode.

Yep, I know some of them watch this list, was hoping they'd chime in,
but now I realize I should have put Solaris in the subject line.

I used to be a Solaris admin but it was a while ago, and I never did
much with the x86 port, so I'm not sure what I should expect to see
under /devices, but there's nothing there that calls itself
"pci"-anything, so I'm wondering if the domU kernel (whether in general
or just in my case) can't see the PCI bus.

I haven't actually tried plumbing the interface yet, maybe I should be
trying to figure out what Solaris calls an nForce ethernet card and give
it a shot...
