Don't do that.

Best practice on RH and Fedora is to install /all/ updates before attempting
troubleshooting.

Running with some packages updated and some not may result in unpredictable
behaviour. Strictly speaking, if an updated package requires another
package to be updated also, the dependencies of the first package /should/
specify this. Mistakes can be made, though.

ACPI state S3 is a sleep mode. Resuming from S3 back into S0 requires that
the CPU be re-initilized.

PAE is Intel's 'Physical Address Extensions', which allow OSs running on
i686 CPUs to address upto 64GB of physical memory.

I'd say it's unlikely that you'll be using /both/ on the same piece of
hardware (i.e. a server that hibernates, or a laptop with >4GB of memory!)

No, it means that agpgart doesn't support your Chipset. This might only be a
problem if you were planning on using hardware 3D acceleration (and even
then, not if you're planning on using an nVidia card, as they provide their
own AGP subsystem independent of agpgart).

Well, from the (out of context) message you've provided, I'd say that's the
case.

Please quote warning/informational/error messages exactly in future.

Also, you'll very often find that googling for the error message you're
interested in - in quotes - finds you explanations of what it means. This
even applies to Windows and other closed operating systems.

Don't use insmod. Use modprobe instead.

slocate uses a cached index of the files on the system. Its cache may be out
of date with what's /really/ present. Can you manually confirm that all
those modules actually exist? Also, what kernel version were you running
when you tried that command? (i.e. run 'uname -r' and reply with the exact
result).

Does FC2 not have /etc/sysconfig/iptables-config like FC3?

I skipped FC2, so I don't know whether it's there, but if it is, using this
is a far cleaner way of loading the netfilter helper modules.
