I can see /sys/devices/virtual/backlight/acpi_video[01]/actual_brightness change when I press the keys, just as /proc/acpi/video/VID/LCD0/brightness does. However there doesn't seem to be anything in sysfs corresponding to /proc/acpi/video/VID1/LCD0/brightness (the one which works).

Looking like a kernel problem again?
