This did not work for me. Could you send me your .config for 2.4.21 +
acpi-20030619-2.4.21?

asus:/usr/src/linux# egrep -i 'acpi|apm' .config
# CONFIG_HOTPLUG_PCI_ACPI is not set
# CONFIG_APM is not set
# ACPI Support
CONFIG_ACPI=y
# CONFIG_ACPI_HT_ONLY is not set
CONFIG_ACPI_BOOT=y
CONFIG_ACPI_BUS=y
CONFIG_ACPI_INTERPRETER=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_PCI=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_SYSTEM=y
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
# CONFIG_ACPI_BUTTON is not set

From "make menuconfig":
