Most laptops have two PCMCIA slots, which may together in "one slot" to speak. Are you positive it is only 1?
If you are concerned about 1 card taking up too much space (many USB cards can occupy two slots), they make dongle-based USB PCMCIA cards which will definitely work in a single slot. And then you can always creatively arrange your PC Cards. Wireless will probably fit on the bottom in a single slot and then a USB card which may occupy two slots would only take up one on the top.
Otherwise, the only solution is to have it repaired a shop, which can get very expensive. The shop I work would charge nearly $150 to $200 for the work... Possibly even more depending on how bad it is. And just to look at it (whether it is repairable or not) is $65.
I happen to do some simliar work myself, at the shop.
