I got the dual-boot stuff working.  Very nice.  Thanks!

I notice one possible problem: it doesn't seem to be possible to boot rockbox when the external power is plugged in and the cowon charging screen is visible.  A short press on power just toggles the backlight.  A long press boots into the cowon fw.  Is there a trick that I missed?

Thanks,

RaeNye:
No, there's no trick unless your nimble fingers can hold the ON button long enough so that the preloader will start the firmware and then quickly release it before the dual-bootloader checks...

I see two alternatives (aside from leaving it as is):
1. Check whether charger/USB is connected and if so, require a longer ON press for OF to load.
2. Add a bypass (e.g., holding REC always boots OF, holding PLAY always boots RB).

The major problem so far is minimizing dependency on the preloader (option 2 has a disadvantage here).

Opinions are welcome.

RaeNye:
Forget opinions, have facts.

Thanks for the update.  Unfortunately, it doesn't seem to work with today's daily.  It builds okay, but the X5 locks up on boot (regardless of charger/length of button hold).  I had to revert to the previous dual boot patch (from 5/12).  That one still works fine.  Not sure why it's failing and, unfortunately, I don't have time to look into it myself nor to try the 5/17 daily.
