What were these errors?

It sounds like the SuSE init scripts are being clever and probably only know about how their 2.4 situation works. What we need is a SuSE person to comment on this behaviour; I don't have access to any SuSE based systems to investigate their quirks.

"still" ? This is news to me (as the guy who seems to be handling both PCMCIA and serial.)

"hang up"? Do you mean "on-hook" or do you mean "stop working"? Is there anything in /var/log/messages about this?
On my RH systems, cardmgr logs a fair amount to the system messages log, which includes details of any commands run and any failures. It would be really useful to see this.
