In general, Mac's don't need additional drivers to read most popular cameras. For example, for my new Casio point 'n shoot, there were pages and pages of instructions on how to hook it up with your Windows PC. For Mac, it essentially said "just plug it in, iPhoto will run and you are done". I would suggest trying this: uninstall any specific drivers you have installed and just plug it in. What happens?
An alternative is to simply buy one of the ridiculously cheap USB or Firewire based camera card readers. These usually come in multi card format, capable of reading CF, SD, Memory Stick and so on. I can tell you from direct experience that OS X needs no additional drivers to read these readers. Just plug in your memory card from your camera and it pops up on your desktop as a new drive.
A good one of these multi card readers can be had for about $25 at any Best Buy, Circuit City or other electronics retailer.
