Each slice can have eight partitions, one of which (c) is reserved. B doesn't have a special meaning anymore - you can swap and dump to any partition you like, and there's nothing to stop you from putting a filesystem on b. D isn't reserved any more, so you can use it for anything you like. A only has a special meaning insofar as the boot code will default to boot off the a partition on the first FreeBSD slice it finds, but otherwise you can use it for anything you like. If "very, very large disks or arrays" really are a problem, you can use a volume manager (such as vinum, or in a pinch, ccd) to split a partition into many logical volumes, each of which can hold a single partition.
