Mac-Mini ACPI wake-on-lan

tl;dr : use ACPI, if you want wake-on-lan you can only suspend to ram

# uname -a

APM

It won't have it :
CONFIG_APM=y
and yet
mini# apmd
No APM support in kernel

ACPI

mini# acpitool -e

   Device       S-state   Status   Sysfs node
  ---------------------------------------
  1. PXS1         S4     disabled   pci:0000:01:00.0
  2. PXS2         S4     disabled   pci:0000:02:00.0

mini# ethtool eth0
Settings for eth0:
... snip ...
        Supports Wake-on: pg
        Wake-on: d

So by default wake-on-lan is disabled (quite right too), thus :
(and *sigh* I have to show you the GPL! - is it really fucking worth it, the notice is longer than the code they gave me) :

mini# cat /etc/init.d/wol
#!/sbin/runscript

depend() {
        need net
}
 
start() {
        acpitool -w | grep -q enabled || acpitool -W 2
        # -W 2 stupidly toggles enabled/disabled
        ethtool -s eth0 wol g
}
 
restart() {
        start
}

so now acpitool -[Ss] both work, I made a swap for storing disk based and it restores just fine, except mplayer waits until a media change before resuming to play on screen (the sound might work, I have it on mute). That's not good enough for this application, it might be an hour. I read some stuff on't'net earlier about dumping video registers and the like and ended up using sys-power/hibernate-script. It didn't do any better so I went for a quick and dirty : kill `{pgrep mplayer}

Or rather I installed daemontools and made mplayer a service (I use SLiM to auto-login to X but I realise now I could have done it with daemontools (I didn't have it installed at the time). Oh well, I learned about xdm.

Hibernate lets you run scripts on resume so I just have it kill mplayer and unclutter (which removes the cursor).

When the Mac-mini is in suspend-to-disk I can't get it to hear Wake-On-Lan magic packets, I have to use the power button to get it to resume. It works just fine with suspend-to-ram (the power led slowly pulses so you know it's on).

TuxOnIce looks like it might help but I can't be arsed with it no more.
