I don't think I have to explain all the steps here. The problem is simple:
The PCIID of the X4500 with B43 chipset is missing in the kernel and the ddx driver sources.
I started X without xorg.conf
I will attach Xorg.0.log and dmesg output

Thanks for the report.
This is the first time I heard B43 chipset. But it does exist and uses X4500:
Let Zhenyu to check spec.
Fabian, could you attach lspci -nvv output? or would you try to add pci ids in kernel agp/intel, drm/i915, xf86-video-intel, and mesa? I can help on if you have issue to add them.

I attached the lspci -nvv output. I can't add the pci ids on my own due to a lack of free time in the next few days and weeks, but I am willing to test patches.

Well, I ignored my schedule for bit and tried to patch the agp/intel and drm/i915 part in the kernel to get KMS support, but dmesg gives me:
Linux agpgart interface v0.103
[drm] Initialized drm 1.1.0 20060810
i915 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
i915 0000:00:02.0: setting latency timer to 64
[drm:drm_fill_in_dev] *ERROR* Cannot initialize the agpgart module.
[drm:intelfb_restore] *ERROR* Failed to restore crtc configuration: -22
DRM: Fill_in_dev failed.
i915 0000:00:02.0: PCI INT A disabled
i915: probe of 0000:00:02.0 failed with error -22
I will attach my patch to the 2.6.31-rc8 kernel. You can also contact me in the #intel-gfx irc channel to speed up patch testing cycles, my irc name is Flyser.

My first try to add the pci ids myself. For the 2.6.31-rc8 vanilla kernel. (see comment #5)
Looks you missed the intel_i965_get_gtt_range() for B43.
I applied all of you patches (http://lists.freedesktop.org/archives/intel-gfx/2009-September/004066.html and following) to the following versions:
And they seem to work fine with KMS support enabled :-)
Do you think I should switch to some git versions of mesa or the ddx, as the X4500 is fairly recent?
Thanks a lot. (Closing as fixed)
Apply to stable releases is just fine, and as our driver rearch has settled down, using git tip is also ok and we must be sure no break on that.
Thanks for report it and testing!
Fabian, thanks for your effort.
Let's keep this bug open until all the patches committed.
We can close this now since all the patches have been committed.
xf86-video-intel: in 184.108.40.2061.
mesa: on master, mesa_7_6_branch, mesa_7_5_branch.
libdrm: on master, will be in 2.4.14 release.
kernel: on drm-intel-next. missing 2.6.31.
