Just checkout https://svn.openmoko.org/trunk/src/host/qemu-neo1973 with
subversion and do this:
http://wiki.openmoko.org/wiki/Talk:OpenMoko_under_QEMU#FreeBSD_and_Qemu...

Then run openmoko/download.sh and openmoko/flash.sh if you have all the
dependencies it should work.

Uh, I thought that this could happen. I have no experience with drivers
like this. But at least it's documented in the User Manual from
Samsung.

Hehe, similar problem here. I wait for the next hardware version as one
should be able to use gps without a linux blob.
