ok, there was only one reply to this problem... from Ralph Dell
( who's seen this problem before.

anyways, i spoke with Sun Tech, and the first problem about "add_spec :
no major #" etc, is nothing to worry about.. its only a problem if you
have a photon disk array attached to your machine. I dont, so we
commented out the line which refers to "sf" from /kernel/drv/sdd.conf
and rebooted. The error went away.

The main problem, the one with pty's and xterms is still unsolved. I
found out what causes it. Sometimes the permissions on /dev/pts are
getting changed automatically from owner-root and group-sys to owner-any
user and group-tty. After this you cant open any xterms on the machines.
Correcting theese permissions and doing a boot -r solves it, until it
happens again. I have no clue whats causing these permissions to change.
I obviously cant keep on doing a boot -r everytime this happens.
