This patch series was tested on a ThinkPad T43.
Can you describe how you did the testing? A specific procedure is
required to test the hotkey NVRAM polling codepaths (which will read
several NVRAM bytes @10Hz by default) in a T43...

The patch looks correct, so I don't expect any problems.
Provided that your test procedure did enable hotkey NVRAM polling in the
T43 and your hotkeys all still worked fine, you have my Acked-by.
The procedure I used was this,
1. $ xev
2. # rmmod thinkpad_acpi
3. Press <Access IBM> key and confirm that xev does not report any
events.
4. # modprobe thinkpad_acpi
5. Press <Access IBM> key and confirm that xev now reports the key press
events.
Is this sufficient?
No. Please try:
modprobe thinkpad_acpi
echo 0xfb88c0 > /sys/devices/platform/thinkpad_acpi/hotkey_source_mask
test the hotkeys. Please test several of them, as not all of them are
available through NVRAM polling... at least Fn+SPACE, Fn+F1..FN+F12
Please test the brightness keys. In the T43 we use "direct EC mode",
which
depends on the NVRAM to sync with the SMBIOS firmware.
to reset the driver to normal mode, it is enough to do this:
echo 0 > /sys/devices/platform/thinkpad_acpi/hotkey_source_mask
