Somebody should really fix/replace this bug tracking system. It's terrible
obfuscated, unusable. I didn't read it [I don't have the time to look for
usable info in that mess].

See how *fdisk work:

  http://lkml.org/lkml/2003/11/30/46

 "that is, if the user has specified a geometry on the command line,
  then that is what we use; otherwise, if there is a partition 
  table already and we are able to guess a geometry from that, use that;
  otherwise, if the kernel has some idea, use that; finally use */255/63
  when no information is available."

For me it make sense and the tools ended up here during a very long
evolution.

So it _seems_ the problem is, parted doesn't try to guess the geometry
from the partition table, just accepts what the kernel says. Bad. But not
knowing parted of course I might be wrong, it's only a first shot guess.

Check the CHS values in the partition table, if you can ...

What tool does the partitioning? What is the kernel?
