lid, with the following output:

hdb: start_power_step(step: 0)
hdb: completing PM request, suspend
hda: start_power_step(step: 0)
hda: start_power_step(step: 1)
hda: complete_power_step(step: 1, stat: 50, err: 0)
hda: completing PM request, suspend
pmac_zilog: 0.00013000:ch-b: suspend, switching to state 2
pmac_zilog: 0.00013000:ch-b: suspend, switching complete
