My web searches on this indicated that when HP first introduced these
systems, they had the same problem with Linux. HP provided a patch
that allows recent Linux kernels to boot. Older i386 FreeBSDs also can
not boot on my HP dc7700. So it appears someone has already fixed this
for i386, but no one has moved it to AMD64.

I don't remember which i386 versions work or don't work, but I can
start booting install disks and find out.
