The 11b/g WLAN card on the T400 is an Atheros AR242x a/b/g PCIe card. I think the b/g is a typo. It does in fact have an A radio. The lastest HAL from MadWifi supports it, and works fine. I suspect that the new HAL for the FreeBSD driver will also support it as well. I wasn't able to test this however. As a side note, the integrated bluetooth also works. >> >> 3.

Under Linux --which is all I can vet for at this time--, all the power management stuff works. It does suspend and resume; however, I've had strange problems occasionally that I don't seem to have if I don't suspend/resume. So, I'd say that it's probably not reliable enough to use dependably. My experience has been that suspend/resume support is generally better under Linux. The only laptop I've ever owned that would reliably resume under FreeBSD was an old Toshiba Portege. That said, this is my first ThinkPad. >> >> 4.

Again, I can't say anything about this for FreeBSD. I'll try to find some time to test the September 8-CURRENT snapshot this week and report back to the list. Overall the T400 is the best laptop I've ever owned in terms of functionality under an OSS operating system, power usage, heat dissipation, noise and build quality. It has none of the heat/fan noise problems reported here with the T40/T60 series. Also, if you do get the T400, the 9-cell battery pack comes highly recommended. I'm getting 4+ hours out of it without any tuning to conserve power and running the screen at ~70% brightness. Take note that, with the LED backlit screen, 100% brightness hurts my eyes. -- Russell A.
