Blacklist drivers builtin to Kernel?

Edit --

This works ---

1) Add blacklist gma500_gfx to /etc/modprobe.d/blacklist.conf
2) Run mkinitfs (which includes the blacklist.conf file)
3) Reboot

======

I am running on hardware that has Intel Embedded graphics. I get a black screen during boot after "loading hardware drivers". I want to disallow the use of the gma500_gfx driver. I have tried various kernel load parameters such as nomodeset and i915.modeset=0 etc, but none of them fix the problem. I have also added blacklist gma500_gfx to /etc/modprobe.d/blacklist.conf (I think that does not effect the kernel).

dmesg output looks like this:
