Thinkpad T40 experience

I've been running FreeBSD on a T40p, which is almost the same, for a while. I 
have run into some issues that it seems you don't have. Would you mind 
sending me a copy of your kernel configuration?

I had no trouble getting it to detect the cardbus controller, though I was 
never able to boot with a device inserted (I had to wait and hotswap them 
during operation). Also, having cardbus support enabled seemed to break 
random things all over, including X crashing upon startup.

I will try and see if the above fix has any effect on that.

Even S1-S2? On my system, only S3-S5 is supported.

I too can get more out of the batteries on Windows then in FreeBSD.

USB dies on my system too, but a resume also has the effect that the system is 
behaving like it's under tremedous load. Typing characters at the console 
feels like I'm ssh:ing over a variable-speed modem :) This makes 
suspend/resume unusable. Did you have to do anything in order for 
suspend/resume to work completely?

Thanks :)
