This looks like a driver bug. On my (non-IBM) i945 chipset, I get
 BACKLIGHT: 255 (0x000000ff) range:  (0,255)
Your driver reports that there is just one possible level of the
backlight, which seems wrong.

The i810 driver is quite old, and has been replaced by the intel driver
quite shortly after introducing XRandR 1.2 capabilities (which is needed
for xbacklight). Try a driver update.
