I recall that when I tried an 040 accelerator on a IIci some time ago it
had problems. I think it might have something to do with the way the
machine maps part of the DRAM for video memory for the internal video. I
forget if using internal video instead of the video card made it go away,
though. Anyway, give that a whirl.

I think the problem stems from the fact that the way the DRAM is mapped for
video changes when you put in an 040 accelerator and NetBSD can't deal with
this condition. Also, when you don't use internal video, I think the
machine changes the memory map and this may be different when running under
the accelerator.

Possibly, but it would seem that NetBSD would have to know that it was
booting a IIci with the accelerator and adjust the way it deals with video
RAM or adjust its understanding of where stuff is mapped.

Anyway, that's my idea. :-) I could be wrong. If you know how to hack a
kernel, it might be worth a try to see if you can fix this.
