Well, I know what I would try, but I'm a programmer-type. :-)

I would open a window/console and run

    strace -o /tmp/x.txt -p [cardmgr_pid]

before inserting the PC card.  The strace(1) command will dump out the
system calls that are being made into the kernel.  Then you can look at
the output of strace (starting from the bottom and working backwards)
to see where you get an error message that corresponds to "Operation
not permitted" (that corresponds to error code "EPERM", so look for a
string that looks like, "-1 (EPERM)" in the output of strace).

Since it's considered bad etiquette to post attachments to the list,
either put the file on the website and post a URL, or email me the
attachment at azhrei-at-eec.com and I'll take a look at it.

(I'm using strace v4.4 from sourceforge at this url:
http://sourceforge.net/project/showfiles.php?group_id=2861)

Hope that helps...
