This is needed to enable accel in the ddx. However,
due to a bug in older versions of the ddx, it relies
on accel being disabled in order to load properly on
evergreen chips. To maintain compatility, we add a new
get accel param and call that from the ddx. The old one
always returns false for evergreen cards.
