[ACPI-sppt] No /proc/acpi with 2.6.0-test1 on IBM Thinkpad R32?!

[ Sorry if this question was asked again and again: I am new to
  the list and the list archives on sf.net are down. ]

Hi

I have a IBM Thinkpad R32 which shows no /proc/acpi:

pfrauenf@lappi:~> ls -lF /proc/acpi
ls: /proc/acpi: No such file or directory

And I wonder if this is my fault, the fault of the kernel, the
BIOS or Saddam's fault. ;-)

I have a kernel.org 2.6.0-test1 kernel (including the patch
acpi-20030714-2.6.0-test1.diff.gz) built with a Debian gcc
3.3.1. The ACPI boot messages read:

pfrauenf@lappi:~> dmesg | grep ACPI
 BIOS-e820: 000000001ff70000 - 000000001ff7a000 (ACPI data)

ACPI: Subsystem revision 20030714
ACPI: Found ECDT
ACPI: Could not use ECDT
ACPI: ACPI tables contain no PCI IRQ routing entries
PCI: Invalid ACPI-PCI IRQ routing table

The ACPI part of my .config file reads:

pfrauenf@lappi:~> grep ACPI /boot/config-2.6.0-test1
# Power management options (ACPI, APM)
# ACPI Support
CONFIG_ACPI=y
# CONFIG_ACPI_HT_ONLY is not set
CONFIG_ACPI_BOOT=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_SLEEP_PROC_FS=y
CONFIG_ACPI_AC=m
CONFIG_ACPI_BATTERY=m
CONFIG_ACPI_BUTTON=m
CONFIG_ACPI_FAN=m
CONFIG_ACPI_PROCESSOR=m
CONFIG_ACPI_THERMAL=m
# CONFIG_ACPI_ASUS is not set
# CONFIG_ACPI_TOSHIBA is not set
# CONFIG_ACPI_DEBUG is not set
CONFIG_ACPI_BUS=y
CONFIG_ACPI_INTERPRETER=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_PCI=y
CONFIG_ACPI_SYSTEM=y
CONFIG_X86_ACPI_CPUFREQ=m
# CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set
# CONFIG_SERIAL_8250_ACPI is not set

The modules fan, ac, button, battery and thermal can be loaded
and unloaded but there is no message in syslog or on console.
And the respective directories in /proc are empty:

pfrauenf@lappi:~> ls -l /proc/ac_adapter/
total 0
pfrauenf@lappi:~> ls -l /proc/battery
total 0

(I thought they should be under /proc/acpi and not under /proc.)

And finally, my BIOS revision: 2.01a (1NET80WW) from 2002-09-12
with Embedded Controller Version 2.29.25 (anything else you need
to know).

Thanks in advance for any hints.

Sincerely
