[Fedora-xen] pciback at boot time

[Gordon McLellan]

I'm having a decent amount of trouble getting pciback to behave the way I'd
like it to.

Originally I found xen-pciback was compiled as a module and not directly
into the kernel, ruling out use of the boot-time argument
xen-pciback.hide=(blah) ... so I recompiled my kernel, incluging pciback
directly into the kernel.

I added my pciback.hide arguments to the GRUB_CMDLINE_XEN in
/etc/default/grub and ran a grub-mkconfig updating /boot/grub2/grub.cfg

The devices were not excluded from Dom0.

So I tried adding the same arguments to the regular GRUB_CMDLINE and the
devices are still not hidden.

Can someone point me in the right direction?  Did I mess up something?
System is FC17 on an x86_64

here's a snippet of my kernel config ... I just noticed that
PCIDEV_FRONTEND=m ... maybe that needs to be set to Y along with
PCIDEV_BACKEND ?
