Same with a PC. See my message above. With CS5 I don't think you need to do the "file preference" thingy that Valdecus mentions.

Yes, there is some difference. RAW files are unprocessed data, so you can change color temperature without damaging the data. You can also recover some highlight data and shadow data.

With a scanned file, you will not have the same latitude with color temperature changes, and whatever highlight and shadow data you have is it (the recovery and fill light slider will not recover any additional data).

"change color temperature without damaging the data."
It looks like that this does also work with scanned film. I tried to correct the white balance of a scanned 4x5" negative which i shoot under fluorescent light and it works great, the file doen`t look damaged.
