Unless its a typo, try "console=/dev/ttyS0" (1 zero, not 2).

Also, if its just a console print problem, you should still be able to
telnet into the box and do things like "cat <file> > /dev/ttyS0" and
"od -x /dev/ttyS0", just to show that the serial device is good and
the problem is with the console device attached to the serial port.

Your console,tty should look something like this:

> ls -l console ttyS0
crw-------   1 root     root       5,   1 Aug  4 10:34 console
crw-------   1 root     tty        4,  64 Aug  4 10:34 ttyS0

I also like to use the following inttab file, instead of
default we ship.   It means there are more places for problems
to exist, but I've seen direct bash drop errors that getty
picks up, like "serial input buffer overrun".

> cat etc/inittab
id:3:initdefault:

# System initialization.
si::sysinit:/etc/rc.sysinit

# Single user shell
1:2345:respawn:/sbin/getty console DT9600 linux

l4:4:wait:/etc/rc.d/rc 4
l5:5:wait:/etc/rc.d/rc 5
l6:6:wait:/sbin/reboot -dip

> cat etc/default/getty
CLEAR=NO
