I wasn't so worry about the driver because the same driver worked with a different application without seeing these kind of messages or oopses.
Dan, from your answer i understand that the swap code discovers a corruption in tables but why is swap code run when swap wasn't activated?
I will try to have a look on the driver code.

  Looks like your driver may have written over some of the page
  tables in the kernel space.

  Those messages are likely due to a bug with swapping to disk
  that has been in some 2.4 kernels, but I don't believe that is
  the case here, since you don't have a disk or swapping enabled.
