My apologies.  This did fix the bug; it's just that there
is another similar one someplace.

I believe we are now crashing in the call to
IopFreeDeviceNode() from LdrInitializeBootStartDriver().
It appears to be on the line:

  RtlFreeUnicodeString(&DeviceNode->ServiceName);

in IopFreeDeviceNode().  Hope this helps, cause I'm
about out of time for today :-)

Also, I notice that when we call IopInitializeDriver() from
IopInitializeService(), we also call IopInitializeDevice();
IopInitializeDriver() seems to also call InitializeDevice()
meaning in that particular case it would be done twice?
