On our linux users group, COLUG. There was mention about Red Hat using 
APM to control pcmcia devices, instead of chkconfig. This was only 
briefly talked about. I was hoping that it went on further. I was able 
to chkconfig with my brief try with gentoo, but never so far with Red Hat.

How would APM and pcmcia services be linked or similar? Maybe that is 
why the subject died off on the local group.
