It's perfectly feasible - the nanox / microwin distribution has been 
used on MicroBlaze before by a PetaLogix client.  There's no magic to 
it, you just need to work methodically through the steps of setting up 
your framebuffer.  The framebuffer virtual console is not necessary, in 
fact seems to cause more pain than anything else.  Much easier to have 
the console on a serial port as per usual, then just launch nanoX which 
will take over the framebuffer.

Regards,

John
