Which version of GNU Parted are you working with?

This problem might go away with GNU Parted 1.8, which will be released
in a few days.

What do you mean by that?  Does it want the end of the partition to be
created in cylinders, or the number of sectors/heads per cylinder?

with fdisk?

Use parted in "unit chs" mode to find a sane setting.
