my keyboard does automatically turn on the backlight depending on
the surrounding lights. I cannot manually control it, but also I
never tried to configure to configure this.

To get backlight at all, I had to enable a few i2c options in the
kernel config, especially the keywest. I suggest to look for them,
in the end I had CONFIG_I2C_KEYWEST=y set and got a backlight
with 2.6.12-rc3 and some of Ben's patches.
