Console on 9000/425t with A1659A graphics

I have a 9000/425t that included A1659A graphics in the SGC slot, and I only seem to be able to use serial console with NetBSD 8.0.

Booting the netbsd-GENERIC kernel via NFS, and using serial console, I see the sti(4) driver come up and recognize the 1280x1024@8bpp framebuffer attached via SGC, and it looks like wscons wants to use it (or is using it), but whenever I’ve tried to boot using local console I get nothing.

Any ideas? I’d love to actually get X11 up on this system. It does work fine with HP-UX 9.10 after all. ;)
