One button click pad - I guess that explains why X only recognizes a
single button. The kernel mis-recognizes it. This is a regression, since
in the 6.x kernels it still works fine.

It is also nothing to do with DRMKMS, it also happens in the GENERIC
kernel. X uses the VESA driver there (which is sub-optimal since it uses
a resolution of 1024 x 768 instead of 1600 x 900).

The assertion failure I mentioned is in this fragment of code, for
reference, line 2833 of src/sys/external/bsd/drm2/dist/drm/i915/i915_gem.c:

2826 static void
2827 i915_gem_object_move_to_inactive(struct drm_i915_gem_object *obj)
2828 {
2829 struct drm_i915_private *dev_priv = obj-base.dev-dev_private;
2830 struct i915_address_space *vm;
2831 struct i915_vma *vma;
2832 
2833 -- BUG_ON(obj-base.write_domain  ~I915_GEM_GPU_DOMAINS);
2834 BUG_ON(!obj-active);
2835 
2836 list_for_each_entry(vm, dev_priv-vm_list, global_link) {
2837 vma = i915_gem_obj_to_vma(obj, vm);
2838 if (vma  !list_empty(vma-mm_list))
2839 list_move_tail(vma-mm_list, vm-inactive_list);
2840 }

Some drmkms success on my laptop

[Rhialto]

I just tried a live image -current on my laptop, and apart from
annoyances with wedges (there is sd0a in the fstab but it is dk7 on my
system (I had transplanted the sd0a partition to sd0f on a
pre-partitioned stick)), X nearly worked.

Only the left mouse button of my touchpad was not recognized.
Which is a weird failure mode that I have never encountered before.
When attaching an usb mouse (actually it was a PS/2 mouse via a
converter), that one worked fine.

Unfortunately, while trying glxgears -fullscreen, there was a reboot
after a while :-(
