 Hey,=20
 
 So I tried today to give the updated patch linked in the email
 thread a spin.
 
 I wasn't able to build the kernel with xorg support (see details
 below) so I could only test it without xorg.
 
 I built NetBSD on the following commit (github)=20
 
 74b93bff118ebb0ab3b384ea79fe9a7c9c62ae20
 
 I applied the patch as is with git am, and didn't do anything to
 fix the whitespace warnings. I built the kernel with the following
 command:
 
 ./build.sh -U -u -O ~/obj -j2 -m amd64 release
 
 I created an installation media and booted into OS with -x -v
 flags, and these were my findings:
 
 $ dmesg | grep -i pms
 [ ...] pms0 at pckbc1 (aux slot)
 [ ...] pms0: synaptics_probe: Not synaptics.
 [ ...] wsmouse0 at pms0 mux 0
 
 $ dmesg | grep -i elan
 nothing
 
 $ dmesg | grep -i iic
 [ ...] iic0 at dwiic0: I2C bus
 [ ...] iic1 at ichsmb0: I2C bus
 
 Since (ostensibly) dmesg doesn't report registering any elan touchpad
 , I didn't think the patch worked and so I didn't bother trying
 further to build with xorg support.
 
 --=20
 The error I got when trying to build NetBSD with Xorg support was
 
 https://paste.sr.ht/~marcc/54861b687ea2bace19a4afb35273ceddf3399582
 
 Fixing the import issues yielded more errors, so I gave up. I
 attempted to buid it on FreeBSD 14
