i had some problems too.
could connect to my laptop but after few seconds it disconnected.
i tried it a few times.
and anyhow it works for me now - with bluemaemo.

i believe these were the steps:
1. remove phone from pc bluetooth-list
2. remove pc from phone bluethooth-list
3. start bluemaemo, click on "wait for connection" and wait a few seconds.
4. on pc search for the device and connect to it (it always was recognized as "phone" when it hadn't worked... when it worked, it was recognized as "unknown" and then had the full HID-functionality)
5. enter pairing code on the phone
6. now it should make a connection automatically (if not i believe, that something went wrong, but you can try it out - if it doesn't work, repeat these steps)
7. try something on bluemaemo - mouse, keyboard for example
