I found a Bluetooth Keyboard Driver for Android, that works with the HID Profile. The good thing is no root required - works on any Android phone.

The initial version also required root priviledges, so it needed extra skills to be used on normal Android devices.

Almost a year after, some considerable development progress has been made and we're now announcing the Teksoft BlueInput for Android, a Bluetooth Driver that allows you to connect a Bluetooth Keyboard to your mobile device for increased typing speed, more productivity, and a new feel of comfort gained by using high tech all arround you.

BlueInput is an advanced HID driver that totally transforms your Android into the perfect Mobile office solution by offering easy Bluetooth connectivity to Bluetooth Keyboards. And it is ready and waiting for you to try it right away.
This application is not free, but the trial version can be used as much as you want, but has a limitation on using the SPACE and ENTER keys.
