If I remember correctly, it is a limit in the DOS partition table
specifications. In practice, I believe you can have both a DOS and a
Linux extended partition. If I remember correctly, DOS/Windows will
ignore a Linux extended partition, but Linux will see both. It has
been a long time sense I played with this, so my memory could be
wrong, or things may have changed to follow the specifications better.

Now, for the original problem. I wonder if parted can expand the
logical partition to use all the free space. This would give you
room for more logical partitions. I have not tried this, so I do not
know if it will work. It might be worth playing with on a drive that
you can afford to trash...
