Well, Robin's problem looks distinctly different than James'.  I believe
Robin's problem has to do with the legacy EEPROM access routines.  The
patchset may have overlooked something in that area.  I just need to
gather evidence to prove it.

I did run some tests this afternoon on a similar IA64 HP machine and
they ran fine.  Consequently, I'm optimistic that James' problem is local
to his machine.  If this turns out to be a wider problem, then I agree
we'll need to find an appropriate solution.
