After more investigation, I have found that
suspend/resume works if I suspend the system from the console
with the command s2disk even if the orinoco module is loaded.

When I suspend the system from the desktop calling pm-hibernate
then there is the delay. Remember, the delay happens on suspend
AND on resume.
pm-hibernate will run a set of scripts in /usr/lib/pm-utils/sleep.d
One of these scripts (45pcmcia) executes:
"/sbin/pccardctl eject" on suspend and
"/sbin/pccardctl insert" on resume.

If I disable this script, then suspend/resume works properly.

I wonder if there are other pcmcia wireles cards that suffer
the same problem?

What is, in your opinion, the proper way to proceed?
To change something in the orinoco driver? Modify pm-utils?
Something else?
