run it through a hash function and it's a good value. Patch that value into the kernel and it's available from the start of the kernel. Then use that value as a key for a HMAC, to hash time values (and other entropy). Do all that and you have a good seed for a PRNG. Unpredictable, different every time, different on all systems.
