Some things to try:
1. Post the output of `acpidump -dt' somewhere -- maybe it will have
clues.
2. Run
dtrace -n 'sdt:thinkpad:hotkey:MHKP { print(args[1]) }'
and then try hitting the hotkeys, and post what comes out. (Hit ^C
when done.)
3. If that doesn't turn anything up, could try:
(a) dtracing fbt::wskbd_input:entry (print args[0]->dv_xname,
args[1], and args[2]) and see if anything interesting comes
out,
(b) building a new kernel to printf what's happening inside
thinkpad_attach to see if that helps, and maybe comparing with
what OpenBSD does.
And, if this is NetBSD 9.x, try NetBSD 10.0_RC3 -- it has had some
changes in the Thinkpad hotkey driver.
