I have just tried a fresh QCX-40 with a fresh 1.03 chip, and the frequency calibration worked fine. Steps:
1) Go to menu 8.13
2) Plug in GPS
3) Wait some seconds until I see satellite lock
4) Turn the rotary encoder one click anticlockwise to 8.12 and wait 6-7 seconds for the Sys Osc cal
5) Turn the rotary encoder one click anticlockwise to 8.11 and wait 6-7 seconds for the Ref Clk cal
6) Unplug GPS
7) Go to menu items 8.5 and 8.6 to check calibrations ran fine
If you have a different sequence of steps and it is failing please can you specify, so I can try that?
Are you sure your fuse settings are correct (no divide-by-8 fuse etc)?
