In the current design the first thing userland has to do is inform
the kernel module about its idea of what the ABI version is.  The 
kernel module can then choose to either support it or return 
EPROGMISMATCH.  If it decides to support it, it will need to 
respect structure sizes corresponding to $CLIENTVERSION.
