Tried it already... The pins are too small to get adequate purchase for
the tape -- the friction just causes it to slide around in the slot and
gets goo around.

Superglue might be a better solution....

...but I think the solder method is better.

On the Radeon 9700 Pro at least there are a couple jumpers on the
appropriate pins, bridged by 0-ohm surface mount resistors (i.e. simple
conductors). What you can do is just unsolder the bridges and it becomes
an AGP 2.0 card... If you have a very steady hand you can also resolder
them to get your AGP 3.0 back.

Still this is not a fun solution as you can potentially cook your card
(make sure to use a 15 watt iron, nothing higher).
