RE: [iPAQ] Booting Linux on the iPAQ

Mark,

We did try this at one point -- we only had one iPAQ to develop on, and we
didn't want to accidentally put it into a nonworking state. But we couldn't
get Linux to boot and our goal was a native Linux handheld, so we stopped
working on it and went straight to a boot from reset. I suspect that we
were not configuring enough devices before re-enabling interrupts, so we
were getting unexpected interrupts.
