2.5.1-pre8 oopses on non existing acorn partition

[Bas Vermeulen]

2.5.1-pre8 oopses in adfspart_check_ICS (probably the put_dev_sector, 
not entirely sure, since there doesn't seem to be anything wrong).
I've enabled advanced partitions, and all the partition types.
Disabling advanced partitions fixes it.

I'm including the output of ksymoops, and hope that it helps,
