deleting GPG UIDs

[MaD dUCK <madduck@madduck.net>]

hey,
i have my GPG key uploaded to the keyservers. unfortunately, i somehow
messed up, and now i have three UIDs associated with it:

fishbowl:~> gpg --list-keys A8FA196E
pub  1024D/A8FA196E 2001-05-07 MaD dUCK <madduck@madduck.net>
uid                            Martin F. Krafft <madduck@madduck.net>
uid                            Martin F. Krafft (MaD dUCK) ...

the last one is unecessary and i would like to delete it...

i can easily do:

fishbowl:~> gpg --yes --edit-key A8FA196E uid 3 deluid save
pub  1024D/A8FA196E  created: 2001-05-07 expires: never      trust: f/u
sub  2048g/E93FAECE  created: 2001-05-07 expires: never     
(1)  Martin F. Krafft <madduck@madduck.net>
(2). MaD dUCK <madduck@madduck.net>

and even upload that key with gpg --send-key, but the keyserver
seems to merge the key rather than to overwrite it. there is no option
to revoke a UID and i can't revoke the entire key.

how can i delete the UID on the keyserver's copy of the key such that
gpg --recv-keys doesn't restore the third UID?
