The existing memory test routine was insufficient to detect certain types
of bus instability related to multiple incompatible RDIMMs on one channel.
Add a PRNG second stage test to the memory test routine. This second stage
test reliably detects faults in memory setup for RDIMM configurations that
also fail under the proprietary BIOS.
