Why I can't see Ubuntu restricted packages

Question

I don't know what else restricted packages are there, but I'm looking for the sl-modem-daemon package, which according to http://packages.ubuntu.com/search?keywords=sl-modem&searchon=names&suite=saucy&section=all, is a restricted package.

I do have restricted repository in my sources.list:

$ grep restricted /etc/apt/sources.list
deb http://us.archive.ubuntu.com/ubuntu/ saucy main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ saucy main restricted universe multiverse
deb http://us.archive.ubuntu.com/ubuntu/ saucy-updates main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ saucy-updates main restricted universe multiverse

And having done apt-get update, this is what I get:

$ apt-cache search sl-modem
sl-modem-dkms - SmartLink software modem driver - module building source
sl-modem-source - SmartLink software modem driver (dummy transitional package)

why the sl-modem-daemon package is not there while the above ubuntu web page says it should be there?

$ lsb_release -a 
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 13.10
Release:        13.10
Codename:       saucy

Thanks

Oh, it has noting to do with the restricted repository, just the sl-modem-daemon package doesn't have the amd64 version in Ubuntu saucy. strange.

$ uname -rm
3.11.0-13-generic x86_64
