1. Any process, including the kernel can only allocate up to 4 GB of memory on a 32-bit system (since a 32-bit integer can only hold that many values) 2. The kernel is further constrained so the user programs can get enough memory 3. Kernel structures for tracking and using memory are also stored in kernel memory. 24 GB of memory with PAE probably "eats up" a lot of those. I think you'll need to increase kmem_size (see http://wiki.freebsd.org/ZFSTuningGuide for an example - ignore ZFS-specific things).
