Can you repackage the binary as a data-only kld, with a couple of public symbols wrapping the beginning and end of the binary, or a couple of symbols with start and length? You could then have the loader pre- load the .ko at boot time. The only other way is to wait until the system is up and load the code into your driver through an ioctl. -- "Where am I, and what am I doing in this handbasket?"
