possible fix

For some reason the current crtc enabled bit isn't going low.  It should be low
already if the crtc is off, but perhaps it has to have been on previously for
it to go low.  I guessing that since this is a ppc system, the card was never
previously posted so the display was off before the driver loaded.  This patch
checks to see what the current state of the crtcs are at driver load time. 
That way we can skip disabling the display if it's already off.  That said, the
messages are harmless in this case.
