I have the exact same problem on my Fujitsu P2110.
Try this patch to acpi_video:
http://am-productions.biz/docs/acpi_video_dpms.patch
It helps (you'll probably get 10-12 hours now) as it will shutoff the
video adapter, but I still have the power drain problem. I'm not
sure what isn't powering down correctly since I've tried to suspend
with all the power management tunables for max power saving.
In my /boot/loader.conf:
hw.pci.do_power_nodriver="3"
