It definitely wasn't the first Unix to have graphics in the kernel,
but it may have been the first commercial one. A number of research
groups modified the V6 kernel to support graphics. This would be
around 1975/76, before the PERQ was produced (early 1980s). The
University of Toronto V6 version had a considerable amount of
graphics code in the kernel, both for vector and raster graphics
as well as high level tablet support. The displays supported were
produced by Three Rivers, so this may be where the motivation for
hte PNX implementation came from.

The University of Toronto modifications to V6 were distributed
through USENIX, and I believe the PUPS archive may have a copy
of it.
