Why 1)?

I wanted to use a (functionally) minimal XEN_DOM0 kernel, so I commented
out the "options CPU_UCODE" line. The build failed with (the source is
CVS: netbsd-6-1-RELEASE):

There is definitely something wrong here: cpu_ucode should not pull out amd cpu_ucode for Xen, but I cannot reproduce that on my host.

Removing "dom0ops" from the config flags has side effects.
