Hi,
I am still trying to optimize hardware support for my Vadem Clio 1050.
Backlight toggle support working with suspend/resume would help save
power and avoid the wince-bootloading cycle.
So I try to get at the correlated hardware / kernel information.
Since I did not manage to boot from the cf-card with
WINCE_DEFAULT_SETTING because of lost interrupts, thanks to the hints
provided by Matthew Orgass I tried the following.

Yes, they do:
I booted 3 times, always with -v option and 10s automatic delay (to
have time to close the display lid). Always using external power and
wifi-pcmcia, alternating through the display swivel modes being open,
in tablet mode and closed.
From there I did a grep for WIN and 'giu data' in dmesg output.

$ cat ./WIN.power.open.wifi
WIN setting:                                iiiiiiiiiiiiiiiilihiilihiiiiilil
$ cat ./WIN.power.tablet.wifi
WIN setting:                                iiiiiiiiiiiiiiiilihiihihiiiiilil
$ cat ./WIN.power.closed.wifi
WIN setting:                                iiiiiiiiiiiiiiiilihiilihiiiiilih

and also

$ cat ./GIU.power.open.wifi
giu data: ......||......|.........|||||||||.|.|||||.|.....||.||||.|.||.|||
$ cat ./GIU.power.tablet.wifi
giu data: ......||......|.........|||||||||.|.|||||.|.....||.||.|.|.||.|||
giu data: ......||......|.........|||||||||.|.|||||.|.....|||||.|.|.||.|||
$ cat ./GIU.power.closed.wifi
giu data: ......||......|.........|||||||||.|.|||||.|.....||.||||.|.||.||.

Hope that helps. Does it sound reasonable?
