I am using the 1st generation of the same CPU on I guess an older dell studio
XPS:
Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz

Have you tried to change the default power setting for your video card?
I have this card:
*-display
description: VGA compatible controller
product: RV730/M96-XT [Mobility Radeon HD 4670]
vendor: Advanced Micro Devices [AMD] nee ATI
physical id: 0
bus info: pci@0000:02:00.0
version: 00
width: 32 bits
clock: 33MHz
capabilities: pm pciexpress msi vga_controller bus_master
cap_list rom
configuration: driver=radeon latency=0
resources: irq:45 memory:d0000000-dfffffff
ioport:2000(size=256) memory:cfef0000-cfefffff memory:cfe00000-cfe1ffff
and have this little file auto-switching my video cards fan from running non-
stop:
cat /etc/local.d/set_radeon_power_profile.start
echo auto > /sys/class/drm/card0/device/power_profile
Apparently, the binary fglrx driver manages power switching more effectively,
but with the radeon driver you'll need to switch it yourself. I can't recall
what I might have had to enable in the kernel, but if you can't get it going
let me know and I'll poke around my .config.

I have the 9-cell battery and it lasts > than 60 minutes while playing video,
browsing, emailing, opening and closing spreadsheets, etc. despite being
almost 4 years old. Since I've set it to auto for video card power management
the battery last longer.
