Ok, will try with 2.6.12

No, but the '--run' flag was set. I noticed that when ommiting the
'--run' flag (like 'mdadm --create /dev/md3 --level=5 --raid-devices=4
/dev/hd[abef]4') the array goes into recovery straight away, so 
probably the '--run' flag forces a '-f'.

It also looks like the '--detail --test' flag of mdadm (to obtain the array
status as return value) does not work (always returns 0). I'll start a
different thread on that when I tested it further.
