Yes, that looks fine.
Have you tested your card with mplayer?
1) set the channel with pvr250-setchannel
2) use something like (g)mplayer -cache 8192 /dev/cxm0 to play.

Do you have PVR-2xx / PVR-5xx in the card setup in mythtv-setup?
First you have to have that choice, or nothing works for the PVR-250.
Ok?

If you have it, you should be able to setup your card by
specifying /dev/cxm0 as the device.

No, but the backend needs a valid card before it will start.
As Bernhard has said, there re problems with the pvrxxx driver and
MythTV > 0.22; they don't communicate very well.

The pvr250 driver might or might not have the same problem, it is a bit
early to tell yet.
More debugging needs to be done.
