Suspend drains battery on IBM T42

I just got a new T42 notebook, and everything works ok, except when I drop
the notebook into acpi sleep, it burns through the battery in 8 hours or
so. It would be nice if the notebook could suspend at least overnight.
I've also noticed that the suspended notebook is warm to the touch. And,
that when the notebook is suspended, the LCD backlight goes off, but the
text is still faintly visible.
This site leads me to believe that my radeon chipset isn't being put to
bed:
http://www.thinkwiki.org/wiki/Problem_with_high_power_drain_in_ACPI_sleep
I'm running 6.0-B5, and I've got acpi_ibm, acpi_video loaded (I kind of
wish suspend/resume would work with drm enabled).
I had tried using apm instead of acpi, but usb fails to work after
resuming, so I didn't test to see if the power drain was better.
I've attached a dmesg, pciconf:
