National ISO in fstab

[Sheedee]

I've got a problem with /etc/fstab.
If I want to mount a vfat partition, only IS9660 encoding (that for CD's) 
is available. Choosing any other ISO norm would result in error message 
saying that the encoding is not supported in kernel. (Which I've recompiled 
and made sure to add support for these encodings...). Have I missed 
something? I know it's propably just my /dev/hands ;), but still I have no 
idea where the problem might be.

Using Fedora Core 1 on Athlon. Trying to mount vfat (Fat32) partition.
