Hybrid graphics problems with radeon/intel setup

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>
tmpfs		/tmp	tmpfs	nodev,nosuid	0	0
UUID=3eb06d84-3a27-4e15-a831-fba544740928 / ext4 defaults,noatime 0 1
debugfs   /sys/kernel/debug   debugfs   defaults   0   0

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Barts PRO [ATI Radeon HD 6800 Series]

#uname -a
Linux clemens 3.3.8-1-ARCH #1 SMP PREEMPT Tue Jun 5 15:20:32 CEST 2012 x86_64 GNU/Linux

Problem 2: I cannot use acpi_call, too:

#lsmod | grep acpi

Maybe someone can help me? Thanks,
raute

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
