The best fix I've come up with so far is enabling laptop-mode and then enabling laptop-mode when on AC power in th conf file you listed above. It seems to work; but it stills dims the screen to black when the AC is unplugged. Oh well, much better than suspending it.

If anybody is versed in C I think it's possible to stop the dimming of screen to black editing /usr/share/acpi-support/power-funcs:
Code:
# a micro library of helper functions for the power scripts

umask 022;

PATH="$PATH:/usr/bin/X11"
POWERSTATE="/var/lib/acpi-support/powerstate"

getXuser() {
        user=`finger| grep -m1 ":$displaynum " | awk '{print $1}'`
	if [ x"$user" = x"" ]; then
		user=`finger| grep -m1 ":$displaynum" | awk '{print $1}'`
	fi
	if [ x"$user" != x"" ]; then
        	userhome=`getent passwd $user | cut -d: -f6`
        	export XAUTHORITY=$userhome/.Xauthority
	else
		export XAUTHORITY=""
	fi
}

getXconsole() {
	console=`fgconsole`;
	displaynum=`ps t tty$console | sed -n -re 's,.*/X .*:([0-9]+).*,\1,p'`
	if [ x"$displaynum" != x"" ]; then
		export DISPLAY=":$displaynum"
		getXuser
	fi
}

getState() {
        /usr/bin/on_ac_power
        if [ "$?" -eq 1 ]; then
                STATE="BATTERY"
        else
                STATE="AC"
        fi
}
        
#check our state has actually changed
checkStateChanged() {
# do we have our state stashed?
        if [ -f "$POWERSTATE" ]; then
                OLDSTATE=$(<$POWERSTATE) 
                if [ "$STATE" = "$OLDSTATE" ]; then
                       exit 0
                else
#stash the new state
                        echo "$STATE" > $POWERSTATE
                fi
        else
#we need to stash the new state
                echo "$STATE" > $POWERSTATE
        fi
}

LAPTOP_MODE='/usr/sbin/laptop_mode'
HDPARM='/sbin/hdparm -q'

LIDSTATE='/var/lib/acpi-support/lidstate'
EDIT: /varlib/acpi-support/lidstate doesn't exist

Have you looked for bios updates? Maybe something saying "we screwed up the acpi event mappings" or enabling battery polling?
