Is your kernel log any different when you experience the long delays?  There is
a 5 second time out for certain display related atombios settings, but when
that happens you'll get a message in the kernel about that.  If you don't see
anything in the kernel logs, you'll probably have to add some debugging
messages to see where the delay is happening.
