The Poulsbo chipset contains a graphics core developed by Imagination Technologies. Intel has licensed the PowerVR SGX as a graphics core and the PowerVR VXD for H.264/MPEG-4 AVC playback. The video core is able to process 720p as well as 1080i resolutions.
Although several netbooks using the Poulsbo chipset are shipped with some distribution of Linux (notably the Sony Vaio P and Dell Inspiron Mini 12, among others), Poulsbo's graphics core GMA 500 is currently not well supported by Intel for the Linux platform.
A proprietary driver was shipped with Dell's adaptation of Ubuntu 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.
Fedora 11 has a working driver developed.
