Fair enough.

What I meant was adding something to the linux command line. I think it was
modeset=1

I tried the kernel command line a week or so ago. I was messing with the
modprobe configuration yesterday so things may have changed between then and
now.

If I use the command line vga=i915 then I get a blank screen until X loads up
(I use kdm)

I am talking about stock debian kernels. Specifically about 2.6.32-1-686 
and the previous 2.6.32-trunk-686.
It has CONFIG_DRM_I915_KMS not set.

I have an intel laptop which has this card according to lspci:
Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02]
(rev 0c)

I am already happy without KMS but I suspect that it won't last.
(KMS will be enabled by default in the kernel at some point maybe?)
