 This turned out to not be caused by changes in NetBSD, but a local change
 to the update method I use on this machine and a machine specific hack
 that script had that I added years ago and forgot - and now overlooked
 during the update of the script.
 
 I forgot the details, but some time ago Jared helped me debug this issue
 and it turned out my machine could not use VESA (I think since I switched
 from BIOS boot to UEFI). Back then we found no easy way to recognize the
 situation and work around it, but instead I started removing the
 vesa modules after each update:
 
 	rm -f /usr/X11R7/lib/modules/drivers/vesa_drv.so*
 
 This makes X work again for me. Difference in Xorg.0.log:
