Dear Richard,

"I" didn't do anything.  It just worked after the installation. So all those
people who developed the relevant software and got it working did all the
important work!  Below are the contents of /etc/sysconfig/apmd.

It won't suspend with the wireless PC card inserted, but there may be some
good reason for it to be that way.

It also worked after installing RH7.2.  I almost exclusively use
<fn>-<f4> and <fn>-<f12> to trigger the suspend and hibernate.

Note:  I have not yet even done this 10 times with RH9.0, so I don't
have the statistical sample to know exactly how reliable it is.
There were a couple of times when I couldn't get the system
to wake up when I was running RH7.2, but I think both times
could be attributed to closing the top (which triggers the
suspend) too soon after starting suspend or hibernate manually.

# the error-beep of your terminal might be set to the default values after a

# if your sound sometimes doesn't work after a resume set RESTORESOUND to
"yes";

# some services might need restarting after a suspend/resume cycle - for

# I got frequent problems mainly with scsi-pcmcia-cards on the cardbus. Use
# PCMCIARESTART="yes" to stop the whole pcmcia-subsystem on a suspend and
# to start it again after a resume. This can slow down your suspend and resume
# process. Use PCMCIAWAIT to wait with the suspend until the pccard is removed
# from the system.
# Some BIOSes are too buggy to handle cardctl suspend and cardctl resume
# properly, in these cases cardctl eject and cardctl insert can be used instead.
# However, this actually ejects the card on hardware supporting it, so if
# the BIOS isn't buggy, it shouldn't be used. Set PCMCIABIOSBUG to yes if
# you are experiencing problems with PCMCIA cards after a resume.
# Since buggy BIOSes seem to be far more common than hardware that can eject
# PCMCIA cards (and it doesn't make a difference on systems that don't have
# either), it is enabled by default.

PCMCIABIOSBUG="yes"
