Default Almost ready to power up

I've got the motherboard finished and I'm checking the voltages before I insert the chips and everything's kind of high, but I suppose that's to be expected with no load.

    Should be        What I'm reading
    ---------        ----------------
      +5                 +11.13
      +9                 +11.90
      -9                  -9.71
     -16                 -18.85
     +16                 +20.00
The one I'm most concerned about is that 11v reading on the 5v line. How's that ever going to come down to 5v with a 15 ohm resistor across the regulator? Any suggestions before I risk blowing all my chips?

Grant, do you have an unpopulated board laying around that you could check the voltages on?
