Useful hints how to configure IBM/Lenovo T60 laptop for Debian GNU/Linux use:

Enable suspend to ram (I'm using stock Debian kernel and uswsusp and tpb)

apt-get install uswsusp tpb

Configure sudo for s2ram using:

/etc/sudoers

dpavlin ALL=NOPASSWD:/usr/sbin/s2ram, /usr/sbin/s2disk

Now configure tpb to suspend to ram on keypress:

/etc/tpbrc

THINKPAD        /usr/bin/sudo s2ram

If you are not using Xsession, you might want to add something like following in .xinitrc

tpb -d

You will also want to add yourself to kmem group:

/etc/group

kmem:x:15:dpavlin
