It is in the state of "works for me". Includes now proper DPMS support. Includes switching between resolutions - from 640x480 to 1024x768. Currently assumes that the native display resolution is 1024x768. The ns2501 seems to be rather critical - if the output PLL is not running, the chip doesn't seem to be clocked and then doesn't react on i2c messages. Thus, a quick'n-dirty trick ensures that the DVO is active before submitting any i2c messages to it. This is probably to be reviewed.
