This commit fixed brightness on my PowerBook5,8 but broke
display.contract in that wsconsctl(8) not fails for this knob:
# wsconsctl display.contrast
wsconsctl: WSDISPLAYIO_GETPARAM: Operation not permitted
display.contrast=0.00%
# wsconsctl display.contrast
wsconsctl: WSDISPLAYIO_GETPARAM: Operation not permitted
display.contrast=4294967293.4294967293%
