Virtuozzo /dev Problems?

I got a Virtuozzo VPS couple a days ago and I am having some problems with it. I can't get a hold of the host because he/she is "migrating" company website at the moment.

VPS OS - Ubuntu 8.04 32-bit
(Initially was 64-bit but I can't even get SSH to work. The host reloaded with 32-bit.)

Initially I was getting some permission problem on /dev/null for regular users. I fixed that with following and stick it in /etc/rc.local

chmod go+rw /dev/null

Now I can't get screen to work. It said something about "No More PTYs.".

$ ls -l /dev/tty*
crw-rw-rw- 1 root tty 5, 0 2009-04-14 14:55 /dev/tty
crw-rw-rw- 1 root tty 4, 0 2009-04-14 14:55 /dev/tty0
crw-rw-rw- 1 root tty 4, 1 2009-04-14 14:55 /dev/tty1
crw-rw-rw- 1 root tty 4, 2 2009-04-14 14:55 /dev/tty2
crw-rw-rw- 1 root tty 4, 3 2009-04-14 14:55 /dev/tty3
crw-rw-rw- 1 root tty 4, 4 2009-04-14 14:55 /dev/tty4
crw-rw-rw- 1 root tty 4, 5 2009-04-14 14:55 /dev/tty5
crw-rw-rw- 1 root tty 4, 6 2009-04-14 14:55 /dev/tty6
crw-rw-rw- 1 root tty 4, 7 2009-04-14 14:55 /dev/tty7
crw-rw-rw- 1 root tty 4, 8 2009-04-14 14:55 /dev/tty8
crw-rw-rw- 1 root tty 4, 9 2009-04-14 14:55 /dev/tty9


(I have "chmod go+rw /dev/tty*" in /etc/rc.local too.)

What can I do or what can I have the host do? I rely heavily on screen for all admin works and I need it to be working. Thanks for your thoughts!
