John Ankcorn is the person primarily responsible for linux kernel
support on the Jornada 720. You can contact him at jca@alum.mit.edu.

You'll see people on this list talk about using hpcboot to try and boot
the kernel all within ram. HP Labs has made available on a very limited
basis flashroms for booting linux on the 720. To my knowledge, no one
has yet booted linux on the 820 off flashroms or in ram.

HTH,
