Dell D600 (not the D610). It's a bit flimsy but everything works. Mine has the 1350 wireless (broadcom)... I use ndiswrapper, no problems using SUSE 9.2/9.3. Can suspend to disk. Accelerated Radeon graphics (I hear that there are variances on what Radeon you might get though). It's not a gamer laptop, but decent enough, small and I know I've used it for over 4 hours without a charge.
I picked mine up refurbed from Dell with a multi-year complete care warranty. First day I had it, the mb had major issues... Dell came out the very next day and replaced it. Haven't had a problem since. We've had it for over a year. Apart from the flimsy case, it's a winner.
The new Dells are better build quality. I own a M70... it rocks.. but is perhaps too large and it only gets a little over 2 hours per charge.
