NetBSD 5.0.2 (XEN_DOM0) #0
>Description:
The amd64 port does not currently support the pciback device.

A separate PR requests multiboot support for amd64.  Together with pciback support, an amd64 xen dom0 could be used for painless driver development in domU instances.

I'm happy to help with the dev. work on this, though I will likely need quite a bit of guidance.
>How-To-Repeat:
On an amd64 xen dom0 with load section boot options such as:

pciback.hide=(01:09.0)

Note that PCI device 01:09.0 will still be configured as normal by NetBSD.

Two reasons for that - no multiboot and no pciback device.

 Where did you get this ? pciback support is x86-specific at this time, but
 not i386 (in fact I did develop it on a amd4 dom0).
 pciback is inclued by default in i386 and amd64 XEN3*DOM0 kernels on the
 netbsd-5 branch.

 My mistake - pciback is not in 5.0.2 - but it is in
 the netbsd-5 branch.

 So please disregard and close this PR and I
 will move to a dev. kernel instead of using a
 release kernel.

 Thanks.
