On x86_64 it works perfectly for me — two different laptops, Intel chipset. On one of them, which is an older MacBook Pro, the touchpad sometimes stops working after resuming, this is easily solved by reinserting its kernel module — you can automate it. On the other one I had to do the same with MediaTek wireless interface, but when I replaced it with Intel one, it started resuming without any issues at all.
There might be issues with particular modules/devices. but in general — it works without a hitch. On most other architectures it's indeed broken.
