The acpiwmibus interface attribute should be handled by combining the
definition in files.wmi with the logic in wmi_acpi.c to call
config_found:
# ACPI WMI mapper
device acpiwmi: acpiwmibus
attach acpiwmi at acpinodebus
filedev/acpi/wmi/wmi_acpi.c acpiwmi
/* acpi_wmi_attach */
I notice a line
acpiwmibus at acpiwmi0 not configured
in the autoconf messages.
Indeed, my kernel config has
acpiwmi* at acpi?
and
wmidell* at acpiwmibus?
but no attachment for any acpiwmibus, nor does any other kernel config.
Is there something magic about acpiwmibus
