Morris Dovey has your answer but a cheap, quick method
is a piece of 1/2" mdf(mdf is your friend) ripped down
to "about" 12" or something wider than the boards you are
trying to straightned out. (plywood is also a option)

Glue,screw,double tape, or what ever method you like
the board in question to the mdf(carrier) and overlap
the board by the amount of rough edge to be removed.

"Slowly" run the sled through the saw using the carrier
against the rip fence. This will produce at least one
straight edge.

I can create a straight sedge on one edge of the lumber ?
