[Xorg-driver-geode] [PATCH] Revert "Added FAQ about minimal memory requirements to rotate screen in README."

[Martin-Éric Racine]

No-Ack.  I don't recall us ever reaching a conclusion that having less
than 32MB under X >>1.6 would produce successful rotations. Anyhow, if
we're gonna correct this FAQ item, I'd rather us fix the minimal
amount of RAM needed for a successful rotation than revert this whole
change.
