I wouldn't know what I was looking at if I did look at the code, but
xorg did complain about missing /dev/io before I added 'io' to the
kernel config.  Then, xorg complained about missing /dev/vga.  So, it
seems to me that adding 'io' fixed the 'missing /dev/io' message, and
adding 'mem' fixed the 'missing /dev/vga' issue, with regards to xorg.

You guys are teaching me a lot!  :)
