I count myself lucky that my laptop is too old to support APCI.
What was so bad about APM anyway? It sure works nice for me:
1) open lid and push space bar (wakes up)
2) my X session is restored in about 1-2 seconds (even before the disk finishes spinning up)
3) close lid on laptop and the BIOS puts it into APM suspend-to-RAM. The equiv of running the 'apm --suspend' command.
Now compare this to my "modern" APCI desktop machine. Until recently Linux won't even handle suspend-to-RAM (I'm not even sure if it does now). Windows which does support it takes about 30-45 seconds to wake up!
That's progress I guess.
