I'm interested in code for all iPaqs with kernel 2.6. But the same 
solution can be used for all PDAs. Now is "model specific" code for ipaq, 
jornada, mypal, zaurus, htc and motorola_ezx.

Code for zaurus (and motorola_ezx) is better - Zaurus::init sets 
m_backlightdev by model and Zaurus::displayBrightnessResolution, 
Zaurus::setDisplayBrightness and Zaurus::setDisplayStatus is common for 
all zauruses with 2.6 kernel.

My concept assume to get "m_backlightdev" automatically by contents 
of /sys/class/backlight/ and /sys/class/lcd/. This will be common for all 
PDAa. I can make code at first for all iPaqs and next we can discuss 
about the right place for that code. May be?
