thanks for helping me.
I know now why acpi_call didn't compile for me, I had the wrong kernel-headers installed.
I can load acpi_call now, but it still won't boot into the graphical desktop.
$ uname -a

Like I said my 1015pn doesn't boot to the graphical desktop, but the stange thing is, when I do
$ dmesg | grep acpi_call
[ 24.121845] acpi_call: Module loaded successfully
[ 24.426121] acpi_call: Calling \AMW0.DSTS 0x90013
[ 24.426847] acpi_call: Call successful: 0x30001
the boot process continues and lightdm starts. I don't have to reboot only launching apt-get remove leads to the start of lightdm...
$ sudo apt-get remove eee1015pn-acpitools
