They say it can be cut to size, but it has to be protected against 
humidity so it has to be sealed again once it's cut. I don't know if it 
would be possible to buy it pre-cut to the K5's LCD size.

One guy succeded with a JKL NDL-205 (Digikey #289-1032-ND). The pins are 
not at the same place so there's a bit of patching to do. I though about 
making little adapter PCBs for this, but my laser printer is dead.and 
needs a $60 part. Perfboard could still work.
