FreeBSD-CURRENT as of today (Wed Mar 6 2002)

>Description:
1) pcvt_ext.c doesn't compile without options XSERVER
2) sc and vt are, afaict, mutually exclusive. i think this should
   be mentioned in NOTES.
>How-To-Repeat:
use a kernel config with:
device		sc	1  
device		vt
and without options XSERVER. try to compile it, watch the
compilation fail, fix the problem by removing the bogus proto-
type, compile, boot.
both sc and pcvt try to create /dev/ttyv0, so pcvt will cause
a panic when it tries to create an already existing device node.
