Hello everyone,
I try to switch between the Radeon HD 6850 and the internal Intel HD2500 of my System.
Problem 1: I cannot use vgaswitcheroo:
# ls /sys/kernel/debug/
acpi bdi dri eeepc-wmi extfrag gpio hid mce regmap sched_features suspend_stats tracing usb wakeup_sources x86
# tail /etc/fstab
# /etc/fstab: static file system information
#
# <file system> <dir> <type> <options> <dump> <pass>

Problem 2: I cannot use acpi_call, too:

Maybe someone can help me? Thanks,

EDIT: Forgot to mention that I use xf86-video-ati and xf86-video-intel. KMS is enabled:
kernel /boot/vmlinuz-linux root=/dev/sda2 ro i915.modeset=1 radeon.modeset=1
