8.04.1 Netbook Remix, which provides 2D hardware acceleration (although users reported serious stability issues) under Linux kernel 2.6.24. A work-in-progress free driver is currently available, however the proprietary driver does not work with current Linux kernels and current versions of X. Work is under way to provide at least 2D support in current Linux kernels, although this will still rely on proprietary binary code for the 3D part of the driver. The current status of this driver runs on Fedora 10 and allows for 2D. 3D acceleration, however, is still broken. A working, proprietary driver package is available for Fedora 11. Starting with Mandriva 2010 Release Candidate 2, Poulsbo drivers are now fully supported out of the box when you use One isos. Hardware will be automatically detected and configured using XFdrake. As it needs non-free firmware, this could not be included in Free isos. A rudimentary (no 3D acceleration) driver was added to Linux 2.6.39.
