I'm not sure.  Perhaps root's umask is set to something
other than 022?

devfs_mk_dir does not take a "mode" argument.  However,
devfs_mk_dir always creates a directory with rx permission
for all, so I suspect that something is wrong with your
devfsd configuration.

A workaround is simply to do
     chown root.thinkpad /dev/thinkpad
     chmod ug+x /dev/thinkpad
on the directory after it has been created.

A more permanent workaround is to add these lines to
devfsd.conf (or in Debian, create the file /etc/devfs/conf.d/thinkpad
with these lines) and restart devfsd, unload and reload
the thinkpad modules:
     REGISTER thinkpad$    PERMISSIONS root.thinkpad  0664
     REGISTER thinkpad$    EXECUTE chmod 0755 /dev/thinkpad

However, you really should find out why the directory perms
are being set to 0666.
