modules_install does not install acpi with linux-2.4.2

Hello,

if I try 'make modules_install' with linux-2.4.2 I get:

...
make[1]: Entering directory `/usr/src_laptop450/linux-2.4.2/drivers'
make -C acpi modules_install
make[2]: Entering directory `/usr/src_laptop450/linux-2.4.2/drivers/acpi'

Indeed I don't have such files in the drivers/acpi-Directory.
laptop450:/usr/src/linux(114)#ls drivers/acpi/
Makefile      acpi_ksyms.o  cmbatt.o  cpu.c  dispatcher/  driver.h

ec.h  events/  include/   namespace/    os.o  power.c  resources/  
sys.o  table.o

My tools should be new enough to work correctly:
laptop450:/usr/src/linux(133)#sh 
/data_tiger/SRC/linux-2.4.1/scripts/ver_linux

In .config I find with respect to ACPI only

Who can help me?
