Ok. Sounds like what I want is to get this patch through the ia64 people, 
after it has gotten some testing there. Since ia64 is where the current 
kernel fails anyway, that sounds like the motivation will be there too.

And there's little point in me merging it until it's been tested to fix 
the actual problem we have now.

Thanks,
