Welp, after trying everything people have asked me to test on this
mailing list, and giving this post a shot:
http://forums.gentoo.org/viewtopic.php?t=122145
I've still been unable to get the G41 to go into suspend mode.  I even
went as far as taking the exact same image that I'm using on my IBM A31
laptop, which works perfectly fine with suspend mode and all, put this
image on my G41, but the G41 still doesn't want to suspend.

I guess I have to come to the realization that this particular model IBM
G41 2886 79U has a broken ACPI and will not work with anything other
than Winblows.  O'well, back to my A31.

Thanks to all that tried to help out!
