With the scripts in this archive, and a little patience, anyone should be able to build the modem packages if they like.
The archive file can be found here:
http://groups.google.com/group/ubuntu-modems/files
There is a README.TXT file with instructions inside.
With these scripts, a person could build a 536/537 modem deb package for Ubuntu Karmic 9.10 in advance if they wanted to.
Also, if anyone is interested in helping out with the project, there are other things that also need doing. The list can be found here:
