SMP ACPI S3 support in 2.4 series?

I'm buying a number of SMP servers. These machines will go
idle for days at a time, and we'd like to send them into a
suspend-to-RAM (ACPI state S3) while they are unused.

I want to know if this is even possible with the Linux 2.4
series kernels, and if so, which hardware and kernel combinations
support it. I'd also like to know if anyone really has this
working right now.

As dual Athlon systems appear to be the best performance/$ for
my application, I'm especially interested in getting those to
sleep, but I'll take any pointers I can get.
