Thank you. I am just in the process of cleaning up the patch and
breaking it into manageable chunks. I've incorporated changes from your
patches and added both your signed-off-by's to the bits you've signed
off on.

OK, I'm boot testing on sles9sp3 and rhel4.4. Perhaps that explains some
of the extra bits you seem to have which I don't seem to need? Or
perhaps they are IA64 specific?

I've left the bits that I've quoted below out for now since I didn't
need them for the releases I'm testing. Once I've committed the first
batch we can revisit these as well as anything I've dropped by mistake.

Cheers,
Ian.
