I've been running Libranet 2.8.1, which is base on debian, for about 3months now. I have everything working on it, except for my resolution. I like to get it running at 1400X1028 but 1028X768 is good enough.
If you're new to linux like me Libranet is a good place to start. Although it cost about $40 but it's the best $40 i spent.
Stuff that's working on my t41:
Kernel: 2.6.6 with 2.6.7 patch
Sound: alsa
dvd/cdrw: works
mouse : synaptic driver
wireless : using ndiswrapper
video: xfree 4.3
Feel free to ask me any questions, i'm not an expert but i can try to help
