Re: [ACPI-sppt] Dell Inspiron 5100: solved (was: Battery and ACPI-OpenGL conflict on Dell Inspiron 5100)

Hello Moritz and others, 

After several changes, it works! Now I have almost complete ACPI support in 
linux-2.4.20.SuSE, available in 2.4 kernels, I hope. Steps are:

* patch your linux-2.4.20.SuSE with following patch for drivers/acpi/osl.c (I 
took it from http://cabibbo.physics.wm.edu/~bryan/computer/inspiron5100.html) 
and modified one line (added 'struct' in line *new_table = (struct 
acpi_table_header*)AmlCode;) --- the patch is at the bottom of this mail.
# patch -p0 -i dsdt.patch
* then, put result of Intel-comiled aml into your kernel:
# iasl -tc Dell-Inspiron_5100_new-A02-custom.asl
# cp Dell-Inspiron_5100_new-A02-custom.hex drivers/acpi/tables/dsdt_table.h
* then copy default configuration of your kernel in kernel root directory:
# cp arch/i386/defconfig .config
# make menuconfig [ put '*' for everything of ACPI ]
# make dep
# made bzImage

You have not to do 'make modules' because you don't do with them anything 
indeed (ACPI support will be integrated into kernel). That's all. In order to 
have OpenGL support, you have to add 'pci=noacpi' on your boot options.

QUESTION: Situation in my /proc/acpi is now as follows:
* ac_adapter: WORKS
* battery: WORKS
* embeded_controler/EC0/info:
	gpe bit:                 0x1c
	ports:                   0x66, 0x62
	use global lock:         no
* fan: EMPTY, DOESN'T WORK
* power_resource: EMPTY
* processor/CPU0:

		    T6:                  75%

		platform limit:          P0:T0
		user limit:              P0:T0
		thermal limit:           P0:T0
thermal_zone/THRM:
	cooling_mode: WORKS, BUT COOLER IS ALWAYS ACTIVE
	polling_frequency: <disabled>
	state, temperature, trip_points: WORK

How does this look? IS IT POSSIBLE TO DO ANYTHING MORE?
