# DECstation Character devices
# CONFIG_VT is not set
# CONFIG_DZ is not set
# CONFIG_UNIX98_PTYS is not set
# CONFIG_KEYBOARD is not set
# CONFIG_MOUSE is not set
# CONFIG_RTC is not set

Same kernel on both the kmin and the MAXine.
I narrowed it down that sys_setup() in fs/filesystems.c gets called
twice on the kmin and only once on the MAXine and there I bumped my head,
how is sys_setup() called? Same thing as with dec_entry().

FYI, enabling CONFIG_VT makes CONFIG_PROM_CONSOLE conflict with the
Sparc one. I'm in favour using a frambuffer console and compiling the
core frambuffer code in the kernel I discovered this.
