checked, that new sa CAM driver takes care of using buffer sizes
<= 64 KB. Was able to dump/restore with block sizes of 96, 128 and
200. using systat -vmstat I noticed transfer blocksizes <= 64KB,
so physio's limits aren't touched.
Since this check was originally from me, I feels safe now to back it
out.
