           Summary: /proc/acpi/wakeup set error
           Product: ACPI
           Version: 2.5
     KernelVersion: 2.6.24-rc6
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Other

Most recent kernel where this bug did not occur: None
Distribution: FC8
Hardware Environment: All
Software Environment: All
Problem Description:
The user can't get any information when echo an invalid value to
/proc/acpi/wakeup although it is failed, but the user can set
/proc/acpi/wakeup successfully if echo an value whose prefix is a
valid value for /proc/acpi/wakeup no matter what the suffix is.

/proc/acpi/wakeup is also case-sensitive, case-insensitive is better.

Steps to reproduce:
