test : t-pvcreate-operation-md.sh
Log message:
update test/t-pvcreate-operation-md.sh attempt loading raid0.ko if raid0
isn't already available (in /proc/mdstat).
switch to requiring 2.6.33 for the alignment_offset tests; 2.6.{31,32}
alignment_offset values aren't reliable. 2.6.33 _should_ have mkp's
alignment_offset fixes but so far it doesn't (as of 2.6.33-rc4).
