These are packages that provide libraries and modules needed to get some level of support for Poulsbo hardware found in some small notebooks such as Dell Inspiron Mini series. Expect nothing fancy — be thankful for panel's native resolution.
The packages are available at http://download.opensuse.org/repositories/home:/lkundrak:/poulsbo/
You can install it by adding a a correct repository (see above) using zypper ar command and in turn run zypper in xorg-x11-psb. If anyone creates an one-click-install shit, feel free to pass it to me and I'll add a link here.
Apart from the kernel module package which was made by me, these packages come from RPM Fusion, which is an add-on repository for Fedora and RHEL and were created by Adam Williamson.
