# mount -a mounts everything in the /etc/fstab file on traditional unix 
systems.  On MacOS X, this should just mount all file systems that 
MacOS X is aware of.

If I plug a Lexar 64MB JumpDrive in, I get the following messages in my 
/var/log/system.log file:

Jan  3 10:23:38 localhost diskarbitrationd[90]: disk1s1    msdos    
00000000-0000-0000-0000-000000000000 MY STUFF                
/Volumes/MY STUFF

Now, if it didn't mount correctly, what I *could* do is type the 
following command:

# mount -t msdos /dev/disk1s1 /Volumes/jumpdrive

This command tells the OS the following: mount the file system located 
at /dev/disk1s1 to /Volumes/jumpdrive, and try mounting it as if it's 
an msdos file system.

Make sense? For more information, check out man mount.
