   Modules are software that can have dependencies.
   I would think you have to compile and then load the i2c_i801 module.
   Otherwise when you attempt to load eee it may fail with unknown symbol in module error
   You should see if the eee.ko compiles before you bother with i2c_i801
   This thread has directions for compiling/installing an in tree kernel module without recompiling the kernel.
   Skip step 5) installing firmware:

   If i remember, Pankso had a flavor for eeepc (i guess he still have one) that includes the eee.ko module. Can't confirm it right know, because the iso used to be hosted at people.slitaz.org/~pankso, that's currently offline.

   Maybe you can try the slitaz-eeepc package on the cooking repos. It brings a script called "tazee" which helps to setup some asus netbooks.

   I proceeded the hard way by recompiling the kernel with i2c_i801 selected in make menuconfig... now I'm having issues compiling eee.c:

   root@servidor:/home/mendel/eeepc-linux/module# make
   make -C /lib/modules/2.6.30.6-slitaz/build M=/home/mendel/eeepc-linux/module modules
   make[1]: Entering directory `/usr/src/linux-2.6.30.6-slitaz'
   CC [M] /home/mendel/eeepc-linux/module/eee.o
   /home/mendel/eeepc-linux/module/eee.c: In function âeee_proc_initâ:
   /home/mendel/eeepc-linux/module/eee.c:399: error: âproc_rootâ undeclared (first use in this function)
   /home/mendel/eeepc-linux/module/eee.c:399: error: (Each undeclared identifier is reported only once
   /home/mendel/eeepc-linux/module/eee.c:399: error: for each function it appears in.)
   /home/mendel/eeepc-linux/module/eee.c:404: error: âstruct proc_dir_entryâ has no member named âownerâ
   /home/mendel/eeepc-linux/module/eee.c:421: error: âstruct proc_dir_entryâ has no member named âownerâ
   /home/mendel/eeepc-linux/module/eee.c: In function âeee_proc_cleanupâ:
   /home/mendel/eeepc-linux/module/eee.c:442: error: âproc_rootâ undeclared (first use in this function)
   make[2]: *** [/home/mendel/eeepc-linux/module/eee.o] Error 1
   make[1]: *** [_module_/home/mendel/eeepc-linux/module] Error 2
   make[1]: Leaving directory `/usr/src/linux-2.6.30.6-slitaz'
   make: *** [all] Error 2

   I think it might be some kind of incompatibility between kernel 2.6.30 and the version used by the author of eee.ko. I'm not a C expert but I'll try to figure out what is wrong with the code

   Thanks

   I dont want make advertisment for puppy, because running only as root is very stupid, but to try things out, you may have a look, if you dont succeed in SliTaz

   Nice tip, kultex! What a pity that the site is offline. I'll try to find Puppeee's source in another place to check how it implemented the FSB control. Thanks

   I finally managed to compile eee.c in 2.6.30.6-slitaz. The avaliable version in https://code.google.com/p/eeepc-linux/ is not compatible with the kernel used by slitaz. Fortunately, there's a version tested with kernel versions up to 2.6.32:

   https://code.google.com/p/eeepc-linux/issues/detail?id=23

   Just one more question before closing the topic: I see in many pages the instructions to add the modules' names to /etc/modules but this file doesn't exist in my slitaz installation. How do I do to set slitaz to automatically load these modules at boot?

   Thanks!

    Hi Mendel,

    I am trying to install this kernel module like a crazy, can you upload the compiled version somewhere?

    maybe you can publish a little tutorial somewhere?

    it would be really usefule.

    thank you
