I bought a Corsair 133x card for my Canon SD550, and it works great.  Makes the camera much faster.  BUT, when I put the SD card in my laptop (Dell D610 WinXP Pro), the OS says it needs to be formatted.  I take the card out, put it back in my camera, and all my pictures are there.  So, I take the card out, put it in my desktop pc (Win XP Home), and the OS says the card needs to be formatted.  I pull the card out, put it in the camera, and the pictures are there.

What drivers do my PCs need to recognize the files on this card?  Both PCs are current with their XP SP2 updates.

You shouldn't need any !   The Corsair cards are both (a) high speed SD cards; and (b) slightly smaller than others.

What readers are you using on the two computers?

... and does the camera work fine as a mass storage class device if you connect it via USB?  (i.e. does the card then "look" like a disk drive??)

Using regular old card readers.  But, funny thing.  I installed the software that came with the camera, and now the PC sees the card and the pictures.  Weird.

... multi-format card readers sometimes have issues with DCIF SD cards (i.e. formatted for a camera) unless they have a DCIF driver in place.   That's apparently what happened here.   Glad it's working :-)
