"server mode" on SMU based machines (Quad G5, iMac G5, ...)

[Benjamin Herrenschmidt]

People keep asking about it ... so I rewrote the tool I whipped up
a while ago and lost :-)

https://gate.crashing.org/~benh/smu_servermode.tar.bz2

It's pretty primitive. Run as root without arguments to query the
current HW setting. Run with argument "0" or "1" to clear or set
the server mode in the SMU.

For those who don't know, "server mode" is when the machine turns
back on automatically after a power failure.

Cheers,
Ben.
