OK, so I gave this another shot (steps below for reference), and things kind of work.

-Use the online image builder (http://www.angstrom-distribution.org/narcissus/) to make an (X11 unstable) image.

-Follow directions to see boot messages (http://wiki.maemo.org/Advanced_booting#Boot_messages)

-Flashed the image, tried to boot; it "couldn't find init on /dev/mtdblock4"

-/sbin/init was linked to /sbin/init.sys-something. I made a copy.

-Tried booting again; complaints about not finding /etc/osso_software_version or some similar file. I created it and put something like RX-... in it (too lazy to look up exactly what- this may be a problem)

-Tried booting AGAIN; get a couple of errors about blocks not being as expected (corruption of some sort?), then it just kind of stops.

Anyway, that's where I'm at now. It also just kind of stopped with the osso_software_version thing. The keyboard still works, so it's not frozen.

Also, a bunch of messages about "cleanmarker" and "empty flash found" pop up during the boot, but stop when init starts.

Any suggestions on what to try? I'm thinking I'll try to reflash it and see if the same stuff happens, but I'd appreciate input all the same.

Sorry about sticking this on this thread, but it seemed to be a direct continuation.

Thanks.

EDIT: Reflashing the image didn't help.
