dunno - not even tried ;)

But now you said that, I tried XFS and it says:
XFS: Attempted to mount file system with blocksize 8192 bytes
XFS: Only page-sized (4096) or less blocksizes currently work.
XFS: SB validate failed

OK
I saw:
http://www.namesys.com/mkreiserfs.html

    -b | --block-size N

    N is block size in bytes. It may only be set to a power of 2 within 
the 512-8192 interval.

and man has the elipsis:
-b N, --block-size=N
              block size (1024, 2048, 4096...)


So I'm sure I'm forgiven ;)
