Dear Owen,
I don't think so, I've just checked looking into the termcap file given
with xterm-164  and the escape sequences for te/ti capabilities are
[?1049h and [?1049l so I think the actual unpatched vt.c is wrong.
I also attached the termcap file,

#
# Note:
#	termcap format is limited to 1023 characters.  This set of descriptions
#	is a subset of the terminfo, since not all features can be fit into
#	that limit.  The 'xterm' description supports color.  The monochrome
#	'xtermm' drops color in favor of additional function keys.  If you need
#	both, use terminfo.
#
#	The 1023-character limit applies to each entry after resolving the
#	"tc=" strings.  Some implementations may discount all or part of the
#	formatting characters in the entry (i.e., the backslash newline tab
#	colon).  GNU termcap does not have this limit.
#
#	I checked the limits using ncurses "captoinfo -CrTv", which prints
#	the resolved length of each entry in a comment at the end - T.Dickey
