Don't remeber where I Originally found this list but I love it:
Possible list from message boards submitted for GM perusal/approval:
• Target is rendered sterile.
• The next person introduced to the target for the first time
will hate him or her uncontrollably forever. Even if this
curse is removed, the person still hates the victim of the
curse, but the victim can improve the person’s attitude

• Each time the target attempts to help a friend or ally, there
is a 50% chance the attempt fails and causes the ally to fail

• Target is struck blind and deaf.
• Each round in combat, there is a 25% chance that the
target will attack the nearest creature rather than choosing
an opponent normally.
• Every time the victim makes a d20 roll, a roll of 20 counts
as a 1.
• The victim effectively ages, moving him or her to the
beginning of the next age category. See Chapter 6 of the
Player’s Handbook for the effects of aging.
• At some point within the next week (or whenever it is feasible),
thieves are able to steal all monetary wealth the
victim has.
• Animals refuse to be within 5 feet of the target and do not
respond to the target’s commands or requests.
• Each time the target meets someone for the first time,
there is a 50% chance that the new person will confuse the
target with a hated enemy, a well-known criminal, or a
raving lunatic.
• All creatures of a specific kind (such as orcs, owlbears, or
black dragons) are permanently invisible to the sight of
the victim (invisibility purge does not help, but see invisibility
and true seeing do). The spellcaster chooses the kind of
creature.
The following effects can be substituted for those given in
the bestow greater curse description (see Chapter 6).
• A random friend or family member of the target contracts
a disease. If the disease is magically cured or runs its
course (regardless of the outcome), another loved one
contracts a new disease.

There was a Dragon magazine article about alternative curses back in 3.5, I think this was the list for Bestow Curse and there was another one for Greater Bestow Curse
