apm powershutown not working in 2.4.20-bf2.4

["J.S.Sahambi" <jsahambi@iitg.ernet.in>]

I just installed the Debian unstable on a P-IV. To power off the system 
when I give it a shuddown we have to load the apm module with option 
"power_off=1". So I give the following commnad:

debain:~# modprobe apm power_off=1


I get the following text on the terminal:


/lib/modules/2.4.20-bf2.4/kernel/arch/i386/kernel/apm.o: init_module: No 
such device
Hint: insmod errors can be caused by incorrect module parameters, 
including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
      /lib/modules/2.4.20-bf2.4/kernel/arch/i386/kernel/apm.o: insmod 
/lib/modules/2.4.20-bf2.4/kernel/arch/i386 
/lib/modules/2.4.20-bf2.4/kernel/arch/i386/kernel/apm.o: insmod apm failed
debain:~#




CAn any body tell me what is wrong?
Thanksing in advance
