Hi Örjan,
 Hmm, it looks like it might take a bit to fix this. Do you want me to
cook up a patch for you that will only run with 256 byte sectors? At
least it would allow some kind of reality check (always a good idea).
There is always the possibility it could bring out some other problems
that might be hideing somewhere.
 In case you're wondering how this is causing your symtoms, with the
patched version, the first partition that is larger than half your disk
size fails the test to see if the partition is larger than your disk
(the extended partition). With both versions there is a dangerous hidden
error. Each partition is created twice the size it is supposed to be.
If you have two partitions, the first will overlap the second. If both
partition were previously formatted on a windows system, the filesystems
should not overlap and seem to be working fine. But if the first
filesystem decides to expand to fill the partition for any reason, you
are toast. This would be good for people that hate M$, but doesn't help
the poor person out in the field trying to get their system going B~).

 Later,
  Paul
