HELP! can't become root POSTSCRIPT

[tom arnall <kloro2006@gmail.com>]

I got impatient with an aumix error and did 'chmod -R /dev' (and ctl-C'ed out 
of it after ~3 min's.) now I can't become root. Some examples:

	kloro@debian:/bin$ sudo /usr/src/modules/alsa-driver/snddevices
	sudo: /etc/sudoers is mode 0777, should be 0440
	kloro@debian:/bin$ su
	Password:
	setgid: Operation not permitted
	kloro@debian:/bin$


When I try to log in as root on a pseudo terminal, I get:

	setgid: operation not permitted

I can log in as myself.

Also, is there other damage that i might have done with the 'chmod'?

Thanks,

tom arnall
