ok man, i have a gateway M305S (or X?) notebook...pretty mucht eh exact same thing as yours. i havent gotten it to work yet, but im almost there.
go to www.intel.com,
search for "linux 82852" and you should come o a few items, just browse around those until you see instructions on how to install the drivers, and instructions on how to download the drivers (on intel's download page). the intel drivers are in RPM format or .tar.gz format.
READ THE INSTRUCTIONS CAREFULLY !!!
you MUST do the make dep thing on you're kernel source for it to work...like i said, follow the instructions. i havent gotten it to work...yet, but im very close.
you may think im crazy because i havent gotten it to work yet though, but here's what i did:
i just untarred the .gz file, and tried installing it...didnt work. so i tied the RPM, and i got errors, and Xwouldn't even start anymore. so i uninstalled it, did the make dep thing, then re-installed it...with no errors. now X windows starts up, but only in 800x600 still, so this is where im stuck. Any help ???
yeah, to put it simply, go to www.intel.com,
and look for the drivers, and while you're there, download the installation .txt file.
