ThinkPad X300

I brought myself a replacement for my broken HP dv2000 in May 2008.

It is fully supported by modern Linux distros, including reliable suspend/resume.

Strange P-states

The Intel(R) Core(TM)2 Duo CPU L7100 @ 1.20GHz in this machine supports three P-states: 1201 MHz, 1200 MHz, and 800 MHz. The 1201 state is unusual. I was informed by Etienne Le Sueur at Linux.conf.au 2009 that these states are reported by ACPI, but can be changed by writing correct values to the systems' MSRs.
