I have fixed several problems and now it boots reliably for both and
older dual Opteron 248 server and an upgraded dual Opteron 280 server.

memtest86+ doesn't work, but according to another mailinglist thread
memtest cannot handle tables in high memory, so that seems to be a
memtest issue.

Attached is a cleaned-up patch. Thanks to Myles and others for excellent
help and support. I hope someone finds the result useful.
