I'm having this exact same problem.  I installed Slackware 9.0 fresh on an
old laptop around about a month ago, and now need Windows 2000 on a
partition for debugging purposes.  I've tried both parted and the commercial
app Partition Magic 8.0 (borrowed the bootdisks from work ;)) with no
success.  The error that Partition Magic drops isn't very useful, but the
error that Parted drops is a tad more workable.

Error: Filesystem has incompatible feature enabled

As I said before, this is a Slackware Linux 9.0 install using the included
2.4.20 kernel with ext3 patches.  Following are logs of both dumpe2fs and
fdisk -l.  I think you'll notice the emerging pattern.
