cd9660_unicode: kernel settings

[Rommel B. IKEDA]

I stumbled upon a port in /usr/ports/sysutils, the name is 
cd9660_unicode-1.0:
It's long description is:
Kernel driver for reading CD disks with non-English filenames.

Since I am using my Gnome2 Desktop in an english environment, when I 
mount CD's containing Japanese names...The icon that shows in my desktop 
is always ",??(???( (invalid unicode)"....I can input/read Japanese 
characters because I am using Canna and Kinput2...

Since I am having this problem, I tried to install the port and after 
installing it says that I can:
Loading the cd9660_unicode Module:
#kldload /usr/local/lib/cd9660_unicode/cd9660_<encoding>.ko
where <encoding> is any name from the following list:
cp775, cp850, cp852, cp855, cp866, iso-8859-1, iso-8859-15, iso-8859-2, 
iso-8859-4, iso-8859-5, jis_x0201, koi8-r, koi8-u, shift_jis...

Since I do not know if my PC is using "jis_x0201" or "shift_jis", I 
wanted to load this 2 encodings in my settings...
The problem is how can I specify them in my kernel so that I can build 
my new kernel...or, what would be the exact lines that I should add in 
my kernel settings to automatically load them...?

I would really appreciate any hints or advice...
