65 = 1 + 64

 1 - A module with a non-GPL license has been loaded, this
       includes modules with no license.
  64 - The user has asked that the system be marked "tainted".  This
       could be because they are running software that directly modifies
       the hardware, or for other reasons.

So, you won't be able to get any help from kernel people (probably)
unless you can reproduce the problem without any binary kernel


Look up some of GregKH's keynote addresses for more background.
