I've raised a but report at:

https://bugs.maemo.org/show_bug.cgi?id=12467

I'm unable to load the necessary kernel modules, even though they're present, despite logging in as root using devel-su

This doesn't look like it will be hard to get working, provided someone can find a way to get the modules loaded.

You can edit /etc/modules as root and add hidp, but this doesn't seem to cause the module to load at boot time.

Sorry.
