XFree86 has a configuration option to select the console
drivers to use in xf86site.def
:
#define XFree86ConsoleDefines -DPCCONS_SUPPORT
#define XFree86ConsoleDefines -DPCVT_SUPPORT
#define XFree86ConsoleDefines -DSYSCONS_SUPPORT
#define XFree86ConsoleDefines -DCODRV_SUPPORT
xf86site.def
the
pccons and pcvt drivers will be supported by default.
Syscons and codrv are not bundled with NetBSD. They are available by anonymous FTP from a number of sites. They are not supported by the XFree86 binary distribution anymore.
