I was setting my Alu G4 Powerbook (15" OSXS 10.3.5, 1.5GHz, 1Gb RAM, 128Mb VRAM, Superdrive)to recieve faxes when it hung with the twirly beach ball thingy. I left it for about a half hour then did an emergency restart. Since then I haven't been able to get it to restart. It will hang on either loading the Firewall IP Settings or Starting the Login Window with the little blue bar cycling but not growing.

I've tried running the Disk Utility off the Startup Cd, repairing the HD and Permissions, reset the PRAM and tried starting in Single User Mode and running sbin/fsck -fy. All tell me that the HD is ok but it still won't restart.

Is there any other way of restarting? I don't really want to have to reinstall the OS.
