I am developing the some of the applications for OpenMoko and I would
recommend setting up an OpenEmbedded rather than using the MokoMakefile.
Instructions can be found here:
http://wiki.openmoko.org/wiki/OpenMoko2007.2#How_to_build

Writing a .bb file to create your ipkg and install it on the device is
then fairly simple. Copying existing ones is often a good way to get
started.

There are thousands of recipes in OE and occasionally a change does
break things. However, I rebuild my environment most days and haven't
had the problems you describe.

A reinstall shouldn't be needed after a software error, unless you were
upgrading. If you have an old version of u-boot it may be worth checking
that you ran 'nand erase rootfs' before flashing the rootfs.

When I had problems with gsmd it would lock the entire phone but it
wouldn't print anything out as far as I know. The following bug report
might be of some help:

The Dialer application should ask for a PIN if required. If it is not
working properly, please file a bug.
