[PATCH] atyfb: VT/GT cleanup
Clean up VT and GT chip descriptions. All B revision VT chips are called 264VT3. Verified from pictures of the chips as the specs are a bit unlear in this. GT revision B1 is Rage II, B2 is Rage II+. Specs and chip pictures seem to agree. VT revision A4 is 264VT2. Revision A3 is probably a plain 264VT.
