Crucial - I believe you are wrong. If you study the details on Crucial, they do say that 1024MB is max.
If you research on usenet (Google Groups), you will find that there was a 512MB module a couple years ago when the T23 came out - but that people had compatibility problems. Kingston / Samsung / Kingmax seems to work fine. The chipset in the T23 is really picky... don't assume that just any old SODIMM will work.
