That makes GEOM taste the card, thus creating the device node(s) for the 
partition(s) on the card. And as long as you don't reboot, the device 
node(s) remain even when you remove the card, so you only need to do 
that the first time you access the card after rebooting.
A dirty hack, but it has worked for me since I started using CF cards on 
a regular basis. Though I would also welcome some kind of automatic 
creation of the device node(s).
