We could actually allocate a larger buffer (dynamically even), but I've
limited it to 6MB since we'd *like* to allocate it from stolen space where
possible, and that's usually limited to 8MB max. It should be easy enough to
try out more dynamic schemes, and allocate from non-stolen memory (since we
generally don't have to worry about the cases where stolen memory is
required), just move the allocation to i830_use_fb_compression() and the free
to the disable routine... I'd be interested to hear how it works for you.
