i'm not using shell layers on our SysV tahoe, but i think
you need to configure the sxt pseudo-device into the kernel.
on our system, the file to edit is /usr/src/uts/machine/cf/CF
(the configuration file).  if you're running a newer SysV
than ours, you may well have the sysadm utility which will
have a "reconfigure kernel" option in a menu.

my System Admin Manual says
"several drivers and software subsystems are treated like device
 drivers without any associated hardware.  To include any of these
 pieces, a pseudo-device specification is used, as shown below:
     pseudo  device-name  [ howmany ]
 Examples of pseudo-devices are sxt, the job-control driver; pty,
 the pseudo-terminal driver (where the optional howmany indicates
 the number of pseudo-terminals to configure--32 is the default);
 and inet... Other pseudo-devices for the network include loop, ...;
 imp ...; and ether ..."

here's the tail-end of our CF file as an example

device		ace0	at vba? csr 0xff0000 vector acecint acerint
device		ace1	at vba? csr 0xff0100 vector acecint acerint
pseudo-device	pty 32
pseudo-device	sxt 8
pseudo-device	loop 1
