The next full release of Debian Linux will include full support for early Asus Eee PC models including the Eee PC 701 and Eee PC 900. That means ethernet and wireless should work without any patches.
The DebianEeePC team has also been releasing patches for other Eee PC models like there’s no tomorrow. You can now find ethernet drivers for the Eee PC 901, 1000, and 1000H and wireless drivers should be available soon as well.
Debian isn’t the first Linux distro to add out of the box support for the Eee PC. You can also install the latest version of Mandriva on most older Eee PCs and expect everything to work without tweaking a thing.
