After a bit of playing around I have fixed this problem. I hadn't copied
the xen0_defconfig from arch/xen/configs/ to arch/xen/defconfig. Now
that I have I get those options back.

There is a bug, however. As long as the .config file has the PCI options
selected then the Bus Options option shows up under X86 Processor
Configuration, (not on the main menu as for usual kernel configures),
but if it is not, or the arch/xen/defconfig file is not in place then it
does not show at all.

FWIW, PCI support _is_ enabled by arch/xen/defconfig, so the cards show
up at that time.

Now all I need is to have access to the MTRR option (CONFIG_MTRR) that
is usually under Processor type and features ... :)
