You haven't told us what distro you're using. Some of them come preconfigured and some don't. In any case you could just try it and see.
If it doesn't work automatically, take a look at this page: http://www.cs.sfu.ca/%7Eggbaker/personal/cf-linux
That info should let you set up support. After that, an fstab entry will make it easy for you (or file browser programs like konqueror) to manually mount the device. If you want true automounting, you'll have to configure whatever auto-mount device your system uses (autofs, supermount).
Edit: Whoops, sorry you did mention FC2. Missed that. I haven't used FC myself, so I can't say anything about it.
