This patch removes the remaining places where assumptions about the structure of the modetable were made. Aside from some places where assumptions are made that certain modes are in the modetable the only code dealing with the modetable and not just a single mode is in viamode. This will allow chaniging the modetable and use other sources for videomodes like the subsystem or EDID.
