You might be able to convince a filesystem to deal in larger block
sizes, but the underlying block IO layer has a physical limit of
PAGE_SIZE due to a somewhat arbitrary design restriction in the
implementation of bios. Unless I've missed a patch and it's already
possible, you could modify the kernel to do what you want but it won't
do it "out of the box".
