Hmm.. I don't have to boot twice. I can switch between Intel and Nvidia the 
same way like using Windows XP. Just switch to preferred mode when laptop is 
poweroff and the selected card works right away (at first boot!).
You only have to boot a second time after your very first boot with acpi_osi 
parameter.

You can adjust brightness of the backlight with "nvclock -S level" (level is a 
value between 15 and 100 or a delta like +10/-10).

That works on my configuration as well.

Btw, i am using Debian sid based distribution (sidux.com) with kernel 2.6.29 
on Vaio VGN-Z21ZN.
