XFS does't support blocksize > PAGE_CACHE_SIZE under linux. In fact the
latest public XFS/Linux release doesn't even support any blocksize other
than PAGE_CACHE_SIZE. This has changed in the development tree now and
the version merged in 2.5 and the next public 2.4 release will have that
support. Doing blocksize > PAGE_CACHE_SIZE will difficult if not
impossible due VM locking issues with the 2.4 and 2.5 VM code.
