This patch splits the acceleration initialization in two parts: The first is only called during probe and is used to allocate resources. The second part is also called on resume to reinitalize the 2D engine. This should fix all acceleration issues after resume most notable an "invisible" cursor and as we do nothing special it is reasonable to assume that it works on all supported IGPs.
