After updating to netbsd-10 and using native org, selected dmesg:

  i915drmkms0 at pci0 dev 2 function 0: Intel UHD Graphics 630 (rev. 0x02)

And X is running fine (displayport 2560x1440)  using the intel driver, snappier scrolling, and no
perceived issues.  I did see:

  [ 2238.2361778] {drm:netbsd:intel_pipe_update_end+0x18f} *ERROR* Atomic update failure on pipe A (start=132807 end=132808) time 151 us, min 1431, max 1439, scanline start 1426, end 1442

but with no obvious ill effects.

so perhaps the VGA connected is only usable with dumb framebuffer, but I
don't really want to use it :-)

I am guessing that if I used the DP daisychain cable the next display
would appear as DP2.

I don't know if HDMI can daisy chain (my monitor can't), but it looks
like additional HDMI sessions over the cable.

So I am a happy camper overall; this felt like by biggest risk with the
new system.

Do we have a wiki page where we record "this graphics hardware worked
with this software"?  It's not 100% an 'port-amd64' thing, so please
feel free to suggest a locaiton if we don't have one already.
