Not all boot scripts properly redirect error messages to the log. They
go to stderr which goes to the console. What is line 8 of config.opts?
And is it a bash script (see line 1)? Probably find it via:
cd /etc
find . -name "config.opts" -print

FYI, I know nothing about PCMCIA, but script errors are not necessarily
PCMCIA even if that is where they were generated.
