I don't have time to check out external repositories. I will only look 
at information included in e-mails posted to the devel list.

I am not sure why you need additional sections in the MMU table for the 
frame buffer. In case it needs non-cachable memory, why don't you put it 
into the .bsp_nocache section?  You can also use a heap for this 
section, see rtems_cache_coherent_allocate().
