What is "unusable" about the built-in flash unit? It should operate just as the *ist DS and other models do: full output, unmetered. You set the shutter speed to anything up to 1/180 sec and set the aperture as required by the ISO and focus distance. A Guide Number chart and instructions to calculate the correct aperture are provided on page 176 in the manual.
I've never seen reliable, credible data on the flash trigger voltage for any of the Pentax DSLR bodies. I've seen reports even from Pentax that differed by reporting anything from 12v to 400v as compatible. So, I look at trigger voltage and if I see anything greater than 10V I'd fit a Wein Safe Sync to protect the camera.
