Hmm, I hope there is some work done on this front (Xv or even openGLES 
based backend for SDL) for Fremantle. The alpha release has same old 
1.2.8-23 SDL version though. Or is there some alternative to SDL for 2D 
graphics?

BTW, as for the external lcd controller status - I have just checked and 
   CONFIG_FB_OMAP_LCDC_EXTERNAL is disabled for both RX-51 
confugurations in Fremantle alpha kernel (unlike e.g. PowerVR stuff) so 
maybe we finally has directly mapped framebuffer in SDRAM ?
