No.  Unless I am greatly mistaken, all PC Cards can be handled
by /sbin/hotplug by 2.4.x drivers and cardmgr should ignore
devices supported by those drivers.  I guess all that's really
needed from pcmcia_cs at this point is cardctl and the config
files.

It shouldn't, since it should be ignoring those devices.

Shouldn't happen, unless you are trying to mix 2.4.x
drivers with pcmcia_cs drivers (can this even work?).
I punted on testing pcmcia_cs stuff a long time ago
and just use the 2.4.x drivers for everything.  Works
for me.

I don't think the beeps are needed, but I suppose we could
make it a configuration setting.  Some people, understandably,
like the reassurance of system feedback telling them that
everything is working as it should be.

If you are using the 2.4.x kernel drivers and pcmcia_cs cardctl
and config files, none of this should be a problem.

The sooner we can supercede pcmcia_cs functionality with
drivers in the kernel tree and a hotplug support package, 
the happier I'll be.
