can you run the test in demos/test and see if it gives sane values for
the pointer?  it might be a rotation issue.

as for the flickering display, I wonder if access to the LCD memory
isn't being properly handled by the framebuffer driver.  could you write
a small test that does memset() on the raw framebuffer to check?  is
there an ioctl() available for synchronization to the LCD?
