You won't be able to flatten a twisted board running it through a planer OR a drum sander.  Doesn't work that way...potato chip in, potato chip out.  You have to get one face flat somehow.  Get out your best low angle plane and sharpen it the best you can.  Then knock off the high spots, check for flat with your winding sticks, then run it through the drum sander.  NOT the planer, as Coop said.  You're asking for an explosion and shrapnel in your face.

 

The alternative is to make a router sled and flatten it that way.  Arguably more work than using a handplane since you have to build a jig.  But then you'll have a jig.  Coin flip.

I never thought about it that way with the ds. I guess, basically you have the same machine with two feed rollers and a flat table. The only difference being one has an overhead drum with blades and the other has sandpaper.

I made a flattening sled for my drum sander. 3/4" melamine and stacks of playing cards under the wobbling board to fill the gaps. Blocks screwed to keep the board from shifting , tape keeps the playing card stacks from shifting. Once you get the top flat take it off the sled and flatten the other side.
