It has been a while since I used maemo-mapper, actually before the february update to OS2007HE. But today I noticed that maemo-mapper is not able to connect to a gps receiver. I have the february HE version, since it allows to change the device language. I had set both the device language and the regional settings to Finnish. I now changed the regional setting to English (UK), keeping the device language as Finnish, and after that maemo-mapper is able to connect to gps. I do also have the recompiled osso-gpsd. Hope this helps someone.
