I have a table with rounded edges. I place warped boards so that they are concave up (edges not touching the table), then with one hand holding the edge and the other pressed flat on the center of the warped part, slowly slide the board over the edge of the table carefully bending it in a direction opposite the warp and about an equal amount to the warp. I do this multiple times if necessary, checking the flatness in between.
For problems getting boards to lie flat that are caused by the board not unfolding "all the way", just flip them over and bend the fold in the other direction just a little. Be careful here as some very low quality board mountings (like Mission: Red Planet) will actually rip right in half.
