Read-only disk problems

Question

Hi,
Yesterday I was stupid enough to perform Repair Permissions from a Tiger system onto Leopard. Results:
-All new folders are read only for me, but read-write for "system". I have to assign myself as read-write every time.
-All non-system fonts are not activated. If I try to activate them with Linotype Font Explorer X, it only remains so as long as I don't quit the app.
-I cannot edit Song info for new imports in iTunes.
-Photoshop CS3 won't start.
-The default apps to open media files are reset.
Etcetera, etcetera. I don't think I have seen all problems yet. I Repaired Permissions several times in Leopard. I also went in single user mode and did
/sbin/mount -uw
chown root:admin /
chmod 1775 /
But it didn't work.
Help would be greatly appreciated.

We found out how to reboot/halt a mini without any filesystem access: Use this
sudo reboot -nq
or
sudo halt -nq
Reference from man reboot
NAME
     halt, reboot -- stopping and restarting the system
SYNOPSIS
     halt [-lnqu]
     reboot [-lnq]
DESCRIPTION
     The halt and reboot utilities flush the file system cache to disk, send all running processes a SIGTERM (and subsequently a SIGKILL) and, respectively, halt or restart
     the system.  The action is logged, including entering a shutdown record into the wtmp(5) file.
     When the system is halted with the halt command, the system is powered off.
     The options are as follows:
     -l      The halt or reboot is not recorded in the system log.  This option is intended for applications such as shutdown(8), that call reboot or halt and log this them-
             selves.
     -n      The file system cache is not flushed.  This option should probably not be used.
     -q      The system is halted or restarted quickly and ungracefully, and only the flushing of the file system cache is performed (if the -n option is not specified).  This
             option should probably not be used.
     -u      The system is halted up until the point of removing system power, but waits before removing power for 5 minutes so that an external UPS (uninterruptible power
             supply) can forcibly remove power.  This simulates a dirty shutdown to permit a later automatic power on. OS X uses this mode automatically with supported UPSs in
             emergency shutdowns.
     Normally, the shutdown(8) utility is used when the system needs to be halted or restarted, giving users advance warning of their impending doom and cleanly terminating
     specific programs.
