 this problem has been diagnosed:
 	- i386 GENERIC has attachments for wsdisplay at both vga(4)
 	  and pcdisplay(4), and this attaches before drm
 	- this means that drm attaches wsdisplay1, and it is unable
 	  to deal with console input or output.
 the workaround is to add these lines to your config:
 	no pcdisplay
 	no vga0 at isa?
 which avoids wsdisplay0 not being owned by drm.
 the real solution is still unknown.  perhaps, simply removing the
 old setup by default?  i don't know what it is necessary for on
 older pc systems.  perhaps some changes to wsdisplay for it to
 recognise some devices are the same, or to force vga@isa or
 pcdisplay to not attach when drm will attach at the PCI location.
