I use a Ralink RT2860 based PCMCIA card in a T41 and it behaves fine.  Not as
strong reception as the built-in Intel Pro Wireless 2100 (ipw2100) that uses
the antenna built into the laptop lid.  It handles crowded environments better
than the ipw2100.  No lockups that I can attribute to it.  Indeed, with
OpenSuSE 11.2 lockups are 1-2/year.
