It should be possible with ivman.
Just compare the output of 'lshal' before and after you plugged in
your smart card; and then add according entries to IvmConfigActions.xml:
<ivm:Match name="hal.XXX" value="TTTT">
  <ivm:Match name="hal.YYY" value="ZZZZ">
   <ivm:Option name="execun" value="xscreensaver-command -lock" />
  </ivm:Match>
</ivm:Match>


Btw, there is http://www.pamusb.org/ - but it works with usb sticks. 
And it's a little bit offtopic here.
