With the fixed-address, the host isn't getting a lease out of the  
_pool_, because it's not dynamically allocated from the pool's range  
statements.  If the options you list should be offered to every host  
that boots in the subnet, move them out of the pool into the  
enclosing subnet and everything should be cool.

If you truly need different options for different pools within the  
subnet (which can be the case for more complex configurations),  
either put default options in the subnet (which the fixed-address  
hosts will get) and override them in the pools, or leave the subnet  
optionless and resign yourself to having to configure the options in  
each fixed-address host declaration.
