APM on a Dell LS running FC2

I picked up a cheap ultralight notebook on eBay the other day and have thrown on Fedora. It's only a P-III 400 and was built in 2000 so it's pre-ACPI. I originally through on FC4 but had problems with it locking up during the, "Initializing Hardware storage network..." phase, so I put on FC2 instead. Just about everything works great under FC2, so I've decided to move into getting Power Management working. I installed laptop-mode-tools via yum and turned on apmd (and disabled acpid both in rc[3,5].d and in grub). Now lapmode works well (I can definitely hear the HDD spin down) however something (I suspect either laptop-mode-tools or apmd) wants to force me to standby after about 2 minutes of inactivity when on battery. The problem is although suspend works (great actually), Standby does not. When it goes into standby, it fails and X stays open with the screen on but the computer is completely locked up. I've searched both /etc/sysconfig/apmd.conf and /etc/laptop-mode/laptopmode.conf and neither seem to offer an option to adjust either the length of time before standby or the ability to switch from standby to suspend. Any idea's what's calling standby?

Also, on a side note, suspend (when called via apm -s) wants the user to be root. I am using the gnome-battery-applet, but it can't suspend since I never log in as root. Is there a simple workaround for this (I imagine with setuid). Besides this, the laptop works great with Linux. The only other hassle was installing Linux in the first place (not because installing Linux was hard, rather because the laptop doesn't have a CDor DVD ROM ).

Well regarding my second question, fixing the setuid part was simple:

chown root /usr/bin/apm;chmod +s /usr/bin/apm

Now any user and call suspend. My bigger problem is still with what's calling standby. I believe I have a workaround, but if anyone has more info please post.
