 Advanced Power Management
 CONFIG_APM
-  APM is a BIOS standard for saving power using several different
-  techniques. This is mostly useful for battery powered laptops with
-  APM compliant BIOSes.  Specifically, the time will be reset after a
-  USER RESUME operation, the /proc/apm device will provide battery
-  status information, and ioctls are provided to put the machine in
-  STANDBY or SUSPEND mode.  This driver does not work for the TI 4000M

+  segment of 0040, which is reserved for the Linux kernel).  If you don't
