If you say yes here you get support for the temperature and
power sensors in various IBM System X servers that support
- PowerExecutive. So far this includes the x3550, x3650, x3655,
- x3755, and certain HS20 blades.
+ PowerExecutive. So far this includes the x3350, x3550, x3650,
+ x3655, and x3755; the x3800, x3850, and x3950 models that have
+ PCI Express; and some of the HS2x, LS2x, and QS2x blades.
This driver can also be built as a module. If so, the module
will be called ibmpex.
