Model: Lenovo Thinkpad T61p 6459-CTO

Distro: Ubuntu Linux 8.04 LTS

• Processor: Intel Core 2 Duo T9300 2.5GHz
  The CPU runs fast and cool.  While idling, it stays somewhere between 40 and 50 Celsius, and goes up to about 60C under load.  For comparison, the CPU in my previous laptop would hit the low 90s under load and idle around 60.
• Video: Nvidia Quadro 570M 512MB
  The video card is well supported by the latest Nvidia drivers.  The Quadro 570M is essentially a Geforce 8600M-GT in terms of hardware, and can draw upon 512MB of memory: 256MB dedicated, and the other 256MB borrowed from the system.
  I’ve yet to put it though any stress tests, but it didn’t have any trouble playing quake 4 at default settings at 1920×1200, though I only tested it for the first minute or so of gameplay.
• Wireless: Intel Wifi Link 4965AGN
  Works out of the box with Intel’s open source driver.  Connects without trouble to my Netgear 802.11n router, and maintains full signal stength throughout the house.

The following also worked out of the box:

• Special buttons, including volume and media controls
• The integrated SD card reader
• Bluetooth

In short, every piece of hardware in the T61p works fine in Linux.  Under the latest Ubuntu release, all I had to do after installing was install the nvidia-new driver from the repositories, everything else is supported by default with open source drivers.
