Serial port naming changed in 2.6.10. Documentation/ia64/serial.txt
has more details.

If you have VGA, that is generally used by default.

IIRC, the zx6000 has these serial ports:

ttyS0 built-in, labelled serial A
ttyS1 built-in, labelled serial B
ttyS2 optional on MP card, UPS port
ttyS3 optional on MP card, console port

So use "console=ttyS0" or "console=ttyS3" depending on which
port you choose.

If you're using a LAN connection to the MP, you still need
to use "console=ttyS3" to select the MP console UART, which
the MP splices into the LAN connection.
