Carp with /30 or 2 different subnets?

I may not just be understanding this correctly, but from what I read I cannot use carp if I am on a /30? My ISP only dishes out /30 subnets, I jut bought a block of static IPs in hopes of setting up an autofail over solution.
Is there anything I can do besides routing my /30 IP down to something usable?

You can still run in failover… But if the primary firewall fails, all your natting etc. Won't work because you need that third ip.
No, you cannot to failover or CARP with a /30 on any currently released version.
With a /30 you only have one IP, the ISP uses the other, so there isn't even an IP for a second node to function.
On 2.2 that should be possible but not ideal, but that's a long way off.
