Lenovo Z570 - Getting "Chipset" related errors and wvdial doesnt work.

[llinux]

Hi,

I was able to install Fedora 15 on my Lenovo Z570 laptop with the following configuration:
IdeaPad Z570 59-069595
Intel® Core i5-2410M
3G DDR3 1333 MHz
640G 9.5mm 5400rpm
Nvidia GeForce GT 520M DDR 3 1GB Graphics

It gave me some "Unknown Chipset" related errors, but I was able to install Fedora 15.

Like Gnome 3 so far

Thing is, I am not able to get wvdial to work.

I am using TATA Photon+ which is like a Wireless USB Modem - Dial In basically. I had to add some parameters and it did work fine after that on Scientific Linux 6/Open Suse 11.4/Mint Linux 11.

I did the same changes in Fedora 15 but its not working.

If someone can help, that will be great.

Also, if this is not the correct forum area to post this, let me know.
