I use the suspend-to-disk-stuff from kernel >=3D2.6.8 with no problems.

as root:

cd /usr/src/linux
make menuconfig

Power management options (ACPI, APM)  --->
[*] Power Management support
[*] Software Suspend (EXPERIMENTAL)
(/dev/hda2) Default resume partition (NEW)

Where /dev/hda2 should be your swap-partition.
Now you can do suspend to disk with

echo -n "disk" > /sys/power/state

At reboot the old state should be loaded automatically.

Have a look at the kernel-docs under /usr/src/linux/Documentation/power/

Bye
Jan
