I checked the contents of /proc/cpuinfo today and discovered that the stated speed in bogomips was 792.57. I know that bogomips != clock speed but when I checked online I found that the jz4770 seemingly performs better on the Novo 7 Paladin:

Does this mean that cpuinfo is incorrectly reporting the processor speed, that the gcwzero is underclocked or that I am misinterpreting the data?
EDIT
/var/log/messages reports CPU speed is 996MHz but I'm puzzled by this line:
Calibrating delay loop... 792.57 BogoMIPS (lpj=1585152)
Is it possible to disable or reduce the length of this "delay loop"?
