Intel’s US15 is a second-generation UMPC chipset.[1] "Code name for low-power chipset for mobile Internet devices. Used with Silverthorne in Intel Centrino, Intel Atom processor technology based machines."[2]

Graphics Core

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.[3]

GNU/Linux Support

Although several netbooks using the Poulsbo Chipset are shipped with some distribution of GNU/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[4]) 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.[5] Work is under way to provide at least 2D support in current Linux kernels,[6] although this will still rely on proprietary binary code for the 3D part of the driver. The current[7] status of this driver runs on Fedora 10 and allows for 2D. 3D acceleration, however, is still broken.
