Hi Gerhard

There are three distinct changes introduced with the bad commit

* the timeout has been decreased - 45 > 9.5 ms
* the DPMS_MODE was explicitly set before + after the DAC detection, but not
any more
* the NV50_PDISPLAY_DAC_CLK_CTRL1 was set at the beginning, whereas the new
version is not touching the register

So one at a time, can you increase the delay back to 45ms
