I very much doubt the reviewer did this. The -server variant (certainly
on one of the Oneiric pre-releases) had CONFIG_XEN_PLATFORM_PCI=m so
it should have been brought in by modprobe. I would guess -virtual
is the same. The installer OTOH does /not/ have the module in the udeb
which is an omission.

I am pretty sure we (eventually) got the standard -server kernel
to boot without rebuilding it, and have /dev/xvda etc. show up.
