What driver are you using? Proprietary drivers don't support KMS.

Oops, I over looked the fact that "intel" was in the title.

I am using xf86-video-intel, which AFAIK is the only one out there,

I had this problem too some time back. For me the system seems to boot in the background but no display. If I added nomodeset to the kernel arguments it would pick up the vesa driver and boot...

The Intel driver needs KMS to load.

I overcame this problem by adding acpi_backlight=vendor to the kernel line in /boot/grub/menu.lst.

Don't know if it is the same issue.

I think this has to something with the Kernel loading the acpi_backlinght driver before the vendor's driver loads. That time i got it from the archwiki.
