Possibly, though we always used to look through links; don't know
about the new tools, but this could be the issue. Could you try a
devfs dom0 and standard dom1?

Is this with the latest repo? I think some changes that went in
last night finally got this functionality working again.

There's something broken with the arch/xen/config.in but I just
can't spot it. The error messages from the Linux config system
are so spectacularly unhelpful that it's impossible to
debug. Fortunately, the error message doesn't actually seem to
obviously break anything, though I have noticed xconfig do
strange things if you ever visit the SCSI config pages.
I think we need to revert to the standard i386 one, and then just
add back in the Xen specific options.
Anyone fancy a really boring but important job? ;-)
