Load balancing a /24 BGP prefix?

Assuming you have a /24 of public IP assigned to you, and BGP peering to 2 different service providers, is it possible to somehow load balance incoming traffic?

I would say "split the subnet into 2 smaller subnets and advertise a longer AS path on each side", but I've heard that you can't advertise smaller than /24? Is this true? And if so, are there any other options?
