I found that in video card driver, it seems that some drawing operations
will call intel_uxa_prepare_access to relocate the frame buffer address
before accessing the frame buffer. So, the frame buffer for Intel Video card
is not a fixed address in video memory ? And is is just mapped to some
system memory (aperture ) ?
