Narrative:

On a return flight to home base, I began taxi to runway 23 at madisonville airport. I announced taxi and reached the end of runway 23 to begin my run-up. (AWOS winds 1706.) at this time I noticed a C210 in the run-up area for runway 5. I called twice over CTAF to find out how long until his departure, but no answer. I announced departing runway 23 and began takeoff roll. At 80 KTS the C210 taxied onto the runway at the far end and stopped. I opted to continue the takeoff and cleared him easily on the 5000 ft runway after also jogging right of centerline to see him out my side of windshield. During climb out I heard the C210 announce his climb out and later call evv approach to report airborne. I reasoned that his entire time on ground was spent monitoring the evv rco and inside the cockpit, not CTAF. This created a dangerous situation in VFR WX.
