Smolt Desktop Profiler from Fedora
This is exactly one feature that gentoo should integrate in its wiki page.
Smolt will get your hardware profile, profile such as what is your audio card, video card and cpu hardware.
Then the profile information will be sent to fedora server which will creates automatically a page containing your hardware profile with link to create a wiki page for your specific hardware.
This program is somehow act like a hardware profile harvester for smolt.org database record. With the options of wiki page for each hardware found, maybe in the future given large enough database, people who wishes to purchase laptop or specific hardware can browse the wiki and find out wether their hardware is supported in Linux or how to install their driver in linux.
