* Set up the framebuffer compression hardware at mode set time. We
* enable it if possible:
* - plane A only (on pre-965)
* - no pixel mulitply/line duplication
* - no alpha buffer discard
* - no dual wide
* - framebuffer <= 2048 in width, 1536 in height
*
* We can't assume that any compression will take place (worst case),
* so the compressed buffer has to be the same size as the uncompressed
* one. It also must reside (along with the line length buffer) in
* stolen memory.
*
* We need to enable/disable FBC on a global basis.
