D'OH!  I forgot about that.  There are two issue here: the sound card
and the nic.

I am running the 2.4.0 kernel with a 2.4.1-pre{mumble} 3c59x driver,
which finally resumes correctly.
For 2.2.18, I put in a kludge to force the apm code to stop/start the
network on suspend/resume.
I was surprised to find that this works really quite well.

Here's what you do: save the enclosed file into
/etc/sysconfig/apm-scripts
The apmcontinue file (which didn't exist in my RH7 setup) is a way to
add extra features to various APM events, like suspend & resume.
Of course, if you already *do* have an
/etc/sysconfig/apm-scripts/apmcontinue file, you will want to merge this
in rather than over-write yours.  ;-)

Regarding the sound card: I've never gotten it to work after a
suspend/resume with any kernel.
I did find that unloading/reloading the module (cs4281.o) will
reinitialize the sound hardware, but since I'm usually logged in and
already have the sounds device open, the module won't unload until I log
out or something similarly inconvenient.
Bottom line: I live without sound.
If someone has a fix for this, please let me know.

   Cheers,
