not sure if your Z1 is the same as my Z690 or if you have another reason 
to prefer the Intel card (power?), but I have only used the Nvidia 
because its the one connected to my DVI port (which I need). The Nvidia 
card works very well with the prebuilt Arch kernel + compiz.

if this is an option for you, what I have done is:

1. added to end of my kernel line in /boot/grub/menu.lst:
# acpi_osi="!Windows 2006"

2. built and installed the modified sony-laptop driver here:

3. added to /etc/modprobe.d/modprobe.conf:
options sony-laptop speed_stamina=3

4. leave my SPEED/STAMINA set on SPEED
