Please commit sdboot and the corresponding patch to disklabel that you
sugested. I did some tests and it seems to work well.

(Beware of the linewarp that my MUA inserted.)

I will commit a patch to sys/arch/hp700/hp700/disksubr.c that fixes the
"boot code is overwritten by disklabel" problem later.

At the moment the kernel doesn't get the correct boot / root device.
I already located the firmware data structure to query the boot / root
device. I can get the HPA / device path of the boot / root device and
now I am working on code to map this into the right struct device *.
So we should be able to auto boot from disk real soon.
