simple patch which fixed problem for me
There is support for eeepc 1005 etc touchpad led. But on my EeePC 1001 HAG it behaves as:
after boot /sys/devices/platform/eeepc/leds/eeepc::touchpad/brightness == 0 and led is off;
when I do 'echo 1 > /sys/devices/platform/eeepc/leds/eeepc::touchpad/brightness', it becomes ==1, but led is still off;
when I do 'echo 0 > /sys/devices/platform/eeepc/leds/eeepc::touchpad/brightness', it becomes ==0, and led is now on.
Unfortunately I hadn't chance to test on EeePC 1005, maybe it is 1001's issue.
re-assign to Henrique.
Sorry Zhang, but I don't take care of Eee-PC ;-)
Maybe you wanted someone else?
re-assign to Corentin. :p
Could you send me your dsdt ?

Thanks, the code for touchpad seems to be the same. Andrej, can you reproduce this bug on your 1005ha ?
close this bug as there is no response for more than 3 months.
Which data is needed? Can I help? (I have not 1005ha...)
does the patch in comment #0 make sense?
the dsdt of semen's laptop is attached in comment #5.

The patch make sense for this model, but I don't know if it won't break on over models with touchpad led, and I didn't get any answer about that (here, and on the mailing list).
Maybe we should apply the patch and wait for a regression report, but I'm not sure that this is a really good practice ...
Reproducable on 1005HA as well, patch from https://bugzilla.kernel.org/show_bug.cgi?id=14865#c0 fixed the problem (kernel-220.127.116.11).
1xxx models should not use eeepc-laptop, they should use eeepc-wmi instead. Please reopen this bug if a model below 1000 is affected or if eeepc-wmi is also affected.

I just tried to use eeepc-wmi, but couldn't load module:
# modprobe eeepc-wmi
FATAL: Error inserting eeepc_wmi (/lib/modules/3.6.38-gentoo/kernel/drivers/platform/x86/eeepc_wmi.ko): No such device
# dmesg | tail
[ 5486.078107] wmi: Mapper loaded
[ 6586.102116] eeepc_wmi: No known WMI GUID found
My device is EeePC 1001 HAG. eeepc-laptop works fine (but with this led bug). Maybe WMI works only for newer models such as 1001PX?..
I guess 1001HA and 1001HAG are the same. if yes you probably need to update your bios. The latest bios update is BIOS 1401 - 2010.03.15.
