i915 module issue (with intel_agp module)

Been googling for solution for some time now...
The laptop I have is Acer TravelMate 5470G, and there are two video cards onboard - Intel and ATI. There is no problem with ATI, but I'd like to use Intel one due to lower power consumption.
Normally I get

Failed to get i915 symbols, graphics turbo disabled

error during starting udev and can't start x (it says there's no display) on xf86-video-intel drivers - must install xf86-video-ati...
So after some googling I blacklisted 'radeon' and 'intel_ips' modules, and added 'i915' module to initramfs - now I get (exactly)

[drmi:i915_init] *ERROR* drm/i915 can't work without intel_agp module!

instead of previous error. I added 'intel_agp' module to initramfs - still the same, and if i lsmod, I see that 'intel_agp' module is loaded.

Can anyone give me some tips, please?

Btw. I'm sure it's technically possible - on windows it's just matter of installing drivers for choosen video card.

It is on the Intel wiki page on how to fix this issue

Re: i915 module issue (with intel_agp module)

Could have written, wiki is always first place I look for resolutions of my problems...
So, wiki quote:

Note: Failing to add i915 to the MODULES array in /etc/mkinitcpio.conf will likely cause the error kernel: intel ips [...]: failed to get i915 symbols, graphics turbo disabled on (at least) the first generation Core i{3,5,7} series processors with integrated GPUs.

and my quote:

(...) and added 'i915' module to initramfs - now I get (exactly)

[drmi:i915_init] *ERROR* drm/i915 can't work without intel_agp module!

instead of previous error.

'Couse that's what mkinitcpio for, rebuilding initramfs, isn't it?

So, I've double-checked now, and, sadly, my issue is not covered in wiki.

Re: i915 module issue (with intel_agp module)

Using i915, I just put i915 and intel_agp into mkinitcpio (you did remember to rebuild, I've forgotten to do that more than once?). I've not needed to blacklist anything, but I don't have a separate graphics card.

EDITED to remove nonsense.

Re: i915 module issue (with intel_agp module)

I was struggling with this warnings/errors for a while. What solved it for me was removing i915 from MODULES in mkinitcpio.conf and adding intel_agp there instead. If I left both i915 and intel_agp there it solved the graphics turbo issue but produced the drm one. Leaving just intel_agp there solved both issues.
And yes, remember to rebuild your initramfs after that.

Re: i915 module issue (with intel_agp module)

Hello,

I have the same problem.

As the wiki said, I tried adding "i915" to the MODULES section of mkinitcpio.conf, and I get "*ERROR* drm/i915 can't work without intel_agp module!" at boot.
It's a new raw install of Arch, nothing installed.

I've tried to put "i915 intel_agp", "intel_agp i915", or even "intel_agp" alone as well. I've also tried to add "i915.modeset=1" to the kernel line in grub's menu.lst file.
Nothing works.

Of course I run "mkinitcpio -p linux" after each change.

I don't really get why it wouldn't work. Another install used to work well a few months ago on the same laptop.

EDIT: It's a dell XPS with an ATI card.

Have you tried disabling your other graphics card in BIOS? I've seen threads where people seem to have had success with that although I've not got a second card myself (only the integrated intel).
