No need to worry guy's, i have found the solution. Simply follow this easy 6 step guide!

1. Buy a Nokia N8
2. Strap the N8 onto the top of your N900, with the bottom of the N8 facing your screen.
3. Install X11VNC on your N900.
4. Install a VNC client on your Nokia N8.
5. Using the VNC client on the Nokia N8, connect to the VNC service running on your N900.
6. Enjoy your N900 with capacitive touchscreen!

Please note, these instructions are untested. While i suggest using a Nokia N8, other devices with capacitive displays may work also, though i suggest sticking with Nokia devices to ensure maximum compatibility.

If anyone tries this out and gets it working, please let me know!
