OK found a solution while reading the disassembled DSDT:
The Code ist checking the OS-Version:

     Method (_PSR, 0, NotSerialized)
     {
       If (LNot (LEqual (FAKE, 0x00)))
       {
         Return (0x00)
       }
       Else
       {
         If (LOr (LEqual (OSFL (), 0x00), LEqual (OSFL (), 0x04)))
           {
              Store (\_SB.PCI0.SBRG.EC0.XCIN, Local0)
                                     }
          Else
           {
              Store (ACIN, Local0)
           }

              Return (Local0)
           }
      }


OSFL is returning 0x00 for win2000 and 0x04 for windows nt.
I defined as a dirty fix:
./include/acpi/platform/aclinux.h:50:
#define ACPI_OS_NAME               "Microsoft Windows NT"

Now the Power Monitor reacts instantly.

Well: the Bios seems to be designed for Microsoft Windows ;-P
