XBMC at GPIO TFT TouchDisplay?

[Eikatis]

Hi all

Want to get XBMC running at my Raspi with 2.8" TFT TouchDisplay.
I know there is a framebuffer driver - but it does'nt work with XBMC. XBMC starts at the HDMI port.
Is there a way to force XBMC GUI at the framebuffer device?
Its a RPi Display with 320x240

I get the console at the display, even videos can play.
But how to get the XBMC GUI on it?

Any idea?
