------- Comment #12 from [EMAIL PROTECTED]  2008-01-11 14:45 -------
So I`m sorry for grammar in my messages.
About toshoba.c I can say that this driver isn`t support toshiba laptops with
phoenix bios. More of all last laptops came with this bios...
--------------------------------------------------------------------
toshiba.c: toshiba.c: toshiba.c: toshiba.c: toshiba.c: toshiba.c: toshiba.c:
toshiba: not a supported Toshiba laptop
--------------------------------------------------------------------
The first line is the result of adding printk messages in the place where
toshiba.c driver check the vendor of bios - it reads vendor from very strange
place, which doesn`t contain this information at all. So there are more checks
that doesn`t passed on my machine... I don`t think that this driver ever will
work on it.

The _INI present in "if" statament, that always true on my machine. So this
function always return -ENODEV. And fn keys doesn`t work bun /sys works!
If I remove this statement fn keys works and /sys doesn`t works. It mean that I
can`t set brithness via /sys/slass/...../brithness. For example so:
echo 100 > /sys/class/backlight/acpi_video0/brightness
This command has no effect. But when I begin change brightness by using fn keys
it change from the value I have set bu the previous command, not from current
LCD brightness!
Also the /sys/class/backlight/acpi_video0/actual_brightness shown the real
value.
So vorks anything expect immediately software brightness control.

another driver - omnibook created for laptop wiht phoenix bios doesn`t work at
all. I have tried to connect with author of this driver, but this afford has no
effect.

Resume: I think that common ACPI subsystem works very well, but there is some
little thing that doesn`t allow this system to work for 100%. I hope that there
is a method to repair it.
