For Starters, Neither one of your links are working. So I can't tell what specific dongle you are trying to connect.
Second, I don't run Linpus. But I will try to help if I can. I installed Easy Peasy 1.1 on my Wifes Acer Aspire one and run Xandros on my Asus EEE 900. I also run AntiX, Ubuntu, And Linux Mint on my other computers.
Linpus Lite is based on Fedora. It has it's own quirks and is a very limited distro/OS. I have read where it has been described as a crippled Fedora. Just letting you know what I know about Linpus. A lot of users go with EEEBuntu 3.0 Standard or Easy Peasy 1.1. Just mentioning it, not suggesting you change.
First off. Have you installed Gnome PPP using Linpus Lite Package Manager or Yum. (I run all apt distros instead of rpm distros so forgive if I don't know all the steps.)
You can refer to this thread to get connected.

That is all you will get from me because I see you have similar threads open in other forums and I won't know what is going on in those.
