[PATCH] ppc64: Fix Fan control for new PowerMac G5 2.7GHz machines

[Benjamin Herrenschmidt]

Hi !

It would be nice if that bug fix could still sneak into 2.6.13 ...

The workaround for broken device-tree that prevents fan control from
working on recent G5 models need to be "enabled" for machines with
revision 0x37 of the bridge in addition to machines with revision 0x35.
