One other thing.  If the aliases you're trying to create are on a 
different network, the subnet mask of the first one has to be the 
"real" mask, and any further aliases in that same network have to use 
a mask of 255.255.255.255.

Example:

ifconfig_fxp0="inet 10.0.0.1 netmask 255.255.255.0"
ifconfig_fxp0_alias0="inet 10.0.0.2 netmask 255.255.255.255"
ifconfig_fxp0_alias1="inet 10.1.1.1 netmask 255.255.255.0"
ifconfig_fxp0_alias2="inet 10.1.1.2 netmask 255.255.255.255"
