You are talking about the kernel built by the xen build system? (e.g.
from "make world" or similar)
For pvops kernels this leverages the upstream "make defconfig" target
with tweaks to enable the Xen stuff. If you think the defconfig is wrong
you should perhaps take this up with upstream.
However, I largely consider the xen build system integration for kernel
building to be a convenience for things like automated test and the
config (or rather buildconfigs/enable-xen-config) to be an example of
the sorts of things which should be enabled on top of your normal
configuration to enable operation under Xen.
I believe xen.org will shortly be publishing daily builds of kernel .rpm
and .deb packages built with a more distro like configuration, I expect
this will be the most convenient and best thing for many users to
consume.
Ian.
