[mythtv-users] OT: wake on lan of slave BE/FE?

Does anyone out there have an nforce 4 based machine with working WOL
from a suspend state (using the forcedeth driver)?  I can wake the
machine from a power-off state using the reversed mac address (known
forcedeth bug), however, it will not wake from a suspend state.  I
have used ethtool to enable the "magic packet" wake-on support in the
driver (apparently wake-on: g means magic packet)

# ethtool eth0
Settings for eth0:
        Supported ports: [ MII ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
        Advertised auto-negotiation: Yes
        Speed: 1000Mb/s
        Duplex: Full
        Port: MII
        PHYAD: 16
        Transceiver: external
        Auto-negotiation: on
        Supports Wake-on: g
        Wake-on: g
        Link detected: yes

I assume since it will wake from a power off (which is controlled by
the bios?) and not from a suspend (which is controlled by software?)
that it must either be a shortcoming on my part to set something
correctly, or less likely, a bug in the driver?  The machine while
suspended, wakes with the pc power button on the MCE remote as well as
any mouse or keyboard activity.  Under windows, I am able to wake the
machine from suspend, after setting "Allow this device to wake the
computer" in device manager.

I'm using 32 bit mythdora 10.2, but I am not sure it is a distribution
specific problem.

Any suggestions?
