yes!its somewhat buggy(just introduced in the 2.6.x kernel...im not sure of x, but it is in 2.6.10 kernel)it uses acpi, turn on software suspend when you configure the kernel, then under /proc/acpi there'll be two files, sleep and wakeup.

to hibernate
echo 4 > /proc/acpi/sleep
be sure to pass the resume=my_swap_partition
option to the kernel

also, to standby(dosen't power off, just less power consumption)
echo 1 > /proc/acpi/sleep
to wakeup
echo 1 > /proc/acpi/sleep

there's more info in
/Documentation/power/swsusp.txt(in the kernel source tree)

i have it working pretty well on my laptop...though for some reason once i resume two problems
-reboots again then resumes
-vt1 is wiped

besides that it works great, good luck!

If your interested on going for the complete bleeding edge there are a host of new suspend and sleep options in the 2.6.11 kernel, though I think most of them are unstable at best.
