Yes, yes it does indeed - thankyou!

However, something else odd has happened.  With the new kernel, I can
start a normal domU as before, but a HVM domU doesn't do anything
much: it appears to get created (interfaces created, appears in "xm
list") but not do anything (doesn't accumulate any cpu time or start
listening for VNC/create a SDL 'console').

I'm sure this is some other problem that's crept in in the meantime,
perhaps even a userland problem with the tools, but it still prevents
me upgrading :-/
