You could probably get rid of 'test server'. It has a bunch of start up scripts as well. I have removed the 'beta' theme on my device ages ago, leaving the alpha theme.

You can also ditch 'osso-startup-wizard' and all of it's startup scripts, however it means if you remove the battery for too long, the system clock will need to be set by hand. It also does something with locales as well, never figured it out.

If you do not have a sim-lock code or device lock code you could probably get rid of the instance of matchbox window manager that is started up prior to hildon to contain the 'enter lock codes' screens.
