Suspend - resume problem

[Patton Echols]

I have recently upgraded my laptop (thinkpad r40) from Edgy to Fiesty.  
I'm still testing, but most things seem to work without tweeking.

However, when I hibernate the laptop and then resume, the function 
buttons for things like screen brightness and sound volume don't work.  
I tried restarting acpi (sudo /etc/init.d/acpid restart) but that has no 
effect.  On the forums found an instruction to add ec_intr=0 to the # 
defoptions line of /boot/grub/menu.lst (and run update-grub).  That does 
not seem to help.

The odd thing is that the system seems to "save" the instructions being 
given by the Fn keys.  I can push the "up volume" button and nothing 
happens if I've suspended.  But after a reboot & login the volume 
indicator flashes and then the volume changes happen.

Anyone have thoughts on where I should go hunting next?
