I still get identical problems with gta01bv4 and the following firmware:
http://buildhost.openmoko.org/OM2007.2/tmp/deploy/glibc/images/fic-gta01/{
u-boot-gta01bv4-1.2.0+git20070917+svnr2943-r0.bin,
OpenMoko-openmoko-devel-image-glibc-ipk-P1-September-Snapshot-20070917-fic-gta01.rootfs.jffs2,
uImage-fic-gta01-latest.bin}

Some logs:

Connected.
[it hung here until, from another terminal, I issued stty -F /dev/ttySAC0 crtscts]
