Kudos! I have to leave a real review of the patches to others more 
qualified than me, but where the previous patch set raised all sorts of 
questions for me, this just looks logical.

I conclude the following from reading the patches:
- a HPA is always at the end of a disk, correct?
- the only case where a user should notice a change after switching
  to 2.6.30 is if he has a partition that starts on or after the
  start of the HPA: such a partition will be ignored (with warning
  in dmesg); I guess that is reasonable as at least it will prevent
  "broken" partitions and is probably relatively uncommon.

Thanks for your continued work on this Bart.

Cheers,
FJP
