I think acpi is the way to go on recent kernels... To get decent
performance I had to apply a patch to the radeon fb code to make it
switch to D2 mode during suspend (use google).

With acpi you must write a short script to respond to lid closure, key
presses etc.
to initiate suspend you do this
echo -n mem > /sys/power/state

You might also want to look in to a sw-suspend (which is disk based)

Have a look at the thinkpad wiki
