Ok, I need to amend my finding and I updated the subject line.
Any idea what changed in the firewire code and if there is a way to reset it
without restarting mythbackend? (fixing 'Power cmd failed (no response)')
So, I can promise you that I had ACPI S3 sleep working and I used to hard
power off my DCH-3200 when my mythtv was sleeping.
When I came back from sleep, everything came back with mythtv 0.24.
I did NOT have to restart mythtv-backend.
Now, I tried not powering off my STB and I noticed that even like that I
still need to restart mythbackend for it to be able to tune channels over
firewire. Before the restart, mythbackend knows that it has a firewire
input, and it shows it as connected, but any attempt to tune channels gives:

2012-05-01 22:36:48.735345 E It appears that your backend may be misconfigured. Check your backend logs to determine whether your capture cards, lineups, channels, or storage configuration are reporting errors. This issue is commonly caused by failing to complete all setup steps properly. You may wish to review the documentation for mythtv-setup.

Restarting the backend fixes this.
Now, I'm forced to leave my STB on because it takes 50 seconds to boot, and
I can't wait 50 seconds for my mythtv to come back from sleep, power on the
STB, then wait 50 seconds, then retart mythbackend, wait another 5 to 10
seconds and only then start mythfrontend.
I swear I didn't have to do with with mythtv 0.24, it just kind of recovered
at runtime. I'm sure it was unable to tune channels on FW for the first 60
seconds, but it did not need to since it woke up from sleep 2mn before the
next recording, or because it was woken up to play saved recordings.
