[Nouveau] better way to test optimus laptop

Hello,
I have an Asus laptop, model U36SD with Nvidia optimus technlogy.
My system has now Fedora 16 with kernel 3.1.0-7.fc16.x86_64
$ lspci -vnnn|grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd
Generation Core Processor Family Integrated Graphics Controller
[8086:0126] (rev 09) (prog-if 00 [VGA controller])
01:00.0 VGA compatible controller [0300]: nVidia Corporation Device
[10de:1050] (rev ff) (prog-if ff)

At the moment, not being able to use optimus technology I compiled
acpi_call (from 24/06/11) for my kernel and set this in
/etc/rc.d/rc.local
/sbin/modprobe acpi_call
echo '\_SB.PCI0.PEG0.GFX0.DOFF' > /proc/acpi/call

Also, due to some video problems for which I don't know if a possible
con-cause could be both nouveau and i915 kernel modules loaded,
I put in my grub.conf settings so that
$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.1.0-7.fc16.x86_64
root=UUID=ce058d6c-d2ed-49e5-9869-965799f246a5 ro rd.md=0 rd.lvm=0
rd.dm=0 KEYTABLE=us quiet SYSFONT=latarcyrheb-sun16 rhgb rd.luks=0
LANG=en_US.UTF-8 i915.i915_enable_rc6=1 elevator=deadline
nouveau.nomodeset=0

$ sudo lsmod|grep nouve
$ sudo lsmod|grep i915
i915                  389156  3
drm_kms_helper         26490  1 i915
drm                   194532  5 ttm,i915,drm_kms_helper
i2c_algo_bit            4958  1 i915
i2c_core               25728  6
videodev,i2c_i801,i915,drm_kms_helper,drm,i2c_algo_bit
video                  12388  1 i915

Is this correct approach at the moment? Anything to test in Optimus
direction and to help nouveau?

Thanks in advance,
Gianluca
