I noticed that too :-)

No, all of syscons dependencies (according to the man page) are still there.

It appears this computer has an i865G chipset (built-in graphics) as
well as an extra nvidia card. The output from devinfo shows that agp is
attaching to hostb0 instead of vgapci0 so I will ask the person to
remove the nvidia card and only run from the built-in graphics. PnP most
likely seems to be the culprit here for sure. Thanks again for your input.
