Do you not have access to CryptGenRandom? CryptGenRandom is FIPS 140-1
approved (at least in Windows 2000). The Windows 2000 version of the
function (which hopefully isn't too different from the CE version) seeds
from 100+ different inputs including: QueryPerformanceCounter, internal
CPU counters, current time, process information like idle process time,
io read transfer count, etc....

I would suspect that CeGenRandom uses a similar (but probably much
smaller) list of inputs. Its probably suitable for nearly everything
except encryption purposes.
