Linux on older laptops

[curt]

Hi All,

This should start a raging debate!
Are there any opinions regarding a good choice of distro for an older laptop?
Thinkpad T22 w/384MB ram and Thinkpad T23 w/512MB ram.
My only priorities are quick boot times, wireless support, firefox or opera 
web browsers and a decent word processor that can save files in .doc format. 
I've considered DSL, but would prefer reiserfs support.

Thanks,
Curt
