Actually, no, you don't.  You get this error message when cardmgr
reads your conf file, regardless of when you insert your card...

What do you intend this line to do?

The error message pops up because you have not defined any PCMCIA
device type that uses the "bullet33_cs" module.  Hence cardmgr can't
do much with your opts specification.

You can only use a "module... opts..." specification if you are
relying on cardmgr to load the driver.  Options for modules that are
autoloaded according to the devicetable stuff should probably go in
/etc/modules.conf.

The whole point of the devicetable stuff is to remove the dependency
on cardmgr.
