Actually, you can subnet these private address spaces any way you choose.  
There is certainly no reason you are limited to octet boundaries.  For 
example, you could have a netmask of 255.255.255.128, and your first two 
subnets would be 192.168.0.0-192.168.0.127 and 192.168.0.128-192.168.0.255.  
The whole point is that these addresses are entirely private.
