Toshiba L30-113A ACPI Ubuntu 7.04

Hi,
In the past few days i became quite frustrated with my Toshiba Satellite
L30-113a laptop. Thing is i can't get the ACPI to work. Or should i say it
works partially, the functional keys work, i got the sound and the wireless
working, yet an important thing in the laptop is not working – namely the
CPU fan. I did some research and found that Toshiba are not very Linux
friendly, yet there must be some solution.

So far i have done this:

I turned on Toshiba support in the ACPI at the kernel and compile it.
The ACPI recognized and displayed the battery and the functional keys

#cat /proc/toshiba/ - missing
#cat /proc/acpi/toshiba - missing

#lsmod | grep acpi

pcc_acpi 14080 0
dev_acpi 12292 0
asus_acpi 17308 0

It is clear that toshiba_acpi is missing and the module is not loaded

#sudo modprobe toshiba_acpi

FATAL: Error inserting toshiba_acpi
(/lib/modules/2.6.20-16-generic/kernel/drivers/acpi/toshiba_acpi.ko): No
such device

#find /lib/modules/`uname -r` -name "tosh*"

/lib/modules/2.6.20-16-generic/kernel/drivers/acpi/toshiba_acpi.ko
/lib/modules/2.6.20-16-generic/kernel/drivers/char/toshiba.ko

Yet the module is present but it's not loaded!

#lsmod | grep cpu

cpufreq_userspace 5408 0
cpufreq_stats 7744 0
freq_table 6048 2 cpufreq_stats,cpufreq_ondemand
cpufreq_powersave 2944 0
cpufreq_ondemand 8876 0
cpufreq_conservative 8712 0

#toshset – says that the module is not loaded

#acpi -V
Battery 1: charged, 100%
Thermal 1: ok, 54.0 degrees C
AC Adapter 1: on-line

#dmesg – nothing suspicious

In what way does the CPU fan not work?  Does it not spin up
when the system is under load?

toshiba_acpi is a reverse engineered platform specific driver,
and it depends on specific code in the ACPI DSDT on toshiba machines.
In this case, it apparently doesn't find that code, and gives up.

Your fan should work correctly even without this driver.

Perhaps you can open a sighting at bugzilla.kernel.org and
attach the output from acpidump?

thanks,
