[subject change and thread breaking]

Working on it.  The RTT on getting tests is going to be long though.

Apparently, I'll have to push ISO images for test *somewhere* that the
HP folks can download, burn to a disk and boot the machines from.

However, they have let me have access for another week and added the
DL580 G7 to the testing as well.  I'll update as I get progress and
debugging.
