IBM Thinkpad and ACPI 20030916 for 2.4.23-pre4

Hi All,
I'm currently using an IBM thinkpad X.31 (latest BIOS). With most recent
IBM thinkpads, ACPI versions prior to 20030916 fail to correctly detect
the Embedded Controller, thus making acpi practically unusable. [1]
There is a patch from Yu Luming that fixes this, but introduces new
errors [1][2] (unable to read battery status).
For 2.6.0-test3 up to test5-mm2, there is a "patch-set" [2] that fixes
most issues, and I have been using it succesfully for several weeks:
[1] http://bugme.osdl.org/show_bug.cgi?id=1038
[2] http://erkki.tty0.org/thinkpad/thinkpad-acpi.html
The output of dmesg with 2.6.0-test5-mm2 with patch[2]:

works fine....
I tried 2.4.23-pre4+ACPI 20030916 and it looks like that only the
"Embedded Controller patch" has been included. I cannot read the status of
the battery:
If I do cat /proc/acpi/battery/BAT0/state I get:
alarm: 2376 mWh
present: yes
design capacity: 47520 mWh
last full capacity: 41070 mWh
battery technology: rechargeable
design voltage: 10800 mV
design capacity warning: 2376 mWh
design capacity low: 475 mWh
capacity granularity 1: 1 mWh
capacity granularity 2: 1 mWh
model number: IBM-08K8040
serial number: 1348
battery type: LION
OEM info: SANYO
present: yes
ERROR: Unable to read battery status
-------------------------------------
If I repeat again, the output of dmesg is (4)
There exists a patch at
[3] http://erkki.tty0.org/thinkpad/kernel/acpi-thinkpad-battery-patch
Has any one else seen this behaviour? For me, it is a regression. Can this
patch be integrated or is there a valid reason not to? I would appreciate
an anwser on this.
Thank you for your work & time.
Regards,
R.
