Great!

Great again, thanks! Patch applied an checked in!

I modified it so that the "default" (no "Backlight" entry in the config) 
is enabled (the call to cfg_number())

Just one thing: you rely on the fact that the backloisht state will be 
applied with the next LCD update. This is not that good, because if 
there's static content, and lcd4linux does a lot of double buffering, 
the next update may be delayed. Is it possible to update the backlight 
immediately?

Just in case you didn't know: you can test your backlight control by 
entering the "interactive mode" with "lcd4linux -i". Then you can call 
your new function by entering "LCD::backlight(1)" or 
"LCD::backlight(0)", and query the current setting with "LCD::backlight()"

Another thing: are you interested in a developer account at SourceForge? 
You could apply patches to your driver yourself... All I'd need is your 
sourceforge account name.

and, finally, me being curious: where are you from? I got two different 
email addresses, one ending in .hu (hungaria?), one .ro (romania?)

bye, Michael (trying to catch some sleep now, need to get up at 5:00 
tomorrow :-(
