Dear all,

I have recently bought a Sony Vaio VGN-Z41WD laptop, and the information 
found in this group was of invaluable help in gettngs most things to 
work. I have been able to fully configure and activate the Intel 4500 
on-board Graphics as well as the Nvidia 9300GS card on a CentOS 5.3 
distribution. I only had to rebuild Xorg 7.4 from source since with the 
outdated version shipped with CentOS 5.3 I could not turn on hardware 
acceleration on Intel graphics (it is a problem common to all newer 
Intel graphic cards). Only one issue is left: the WWAN card. The only 
way to use it is activate it under Windows Vista, then reboot (without 
the "acpi_osi=!Windows 2006" kernel option or Windows settings will be 
erased, which means that it is impossible to activate the Nvidia card if 
one wants to use the WWAN module). I read some posts explaining how to 
make it work using the gobi firmware loader 
(http://www.codon.org.uk/~mjg59/gobi_loader/), but I was not successful. 
The main problem is that, unless one boots in Windows Vista first, the 
WWAN module is not even listed among USB modules by lsusb. Can someone 
give any help on this point?

Best regards,
Paolo Tosco
