The touchscreen driver kernel module controls the power button
("h3600_ts"). It has a mode switch named
"/proc/sys/ts/suspend_button_mode" that controls the power button
behavior: 0=enabled, 1=treat as normal button. You can check the value
of this with "cat /proc/sys/ts/suspend_button_mode" (or set it using
(e.g.) "echo '0' > /proc/sys/ts/suspend_button_mode.

This parameter is initially set on module load, so you may find a line
like "options h3600_ts suspend_button_mode=1" in your
"/etc/modules.conf" file.

Is it possible that the iPAQ was in VESA screen-saver mode? That's
where the iPAQ powers off the LCD screen, but continues to run.

Did you try running the "bl" program directly? Can it turn your
backlight on and off?
