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.

Thanks,
Jesse
