Ok, but still - won't I have issues with EXA's memory manager when, for
instance, EXA allocates an 8bpp pixmap 10x10 but when the CPU accesses it I
expand it to 32bpp internally, meaning it takes up 10x40 so more linear
addresses are actually used. How can I bypass this? are there hooks in the
memory manager too?
