If you do this, please consider allowing a block size up to 64KB. The ia64 kernel offers a choice of 4, 8, 16, and 64KB page size.

ia64 linux normally uses > 4KB. The recommended page size at the moment is 16KB. I didn't think 64KB would become realistic for quite some time, but performance is surprisingly good, even on today's systems.
