I'm not sure it's worth going to the extent of having /proc
entries that provide this when it's pretty easy just to knock up
a little application that uses priv_cmd to fetch it, e.g. to
write core dumps.  (I think someone may have already done this?)

I guess I haven't totally swallowed the Plan-9 everything-is-a-file pill ;-)

Switch the serial line to Xen (hit ctrl-A 3 times), then hit
'q'. This dumps the register state of all domains and triggers
the debug interrupt on each of them.
