xen doesn't have a 'console=' cmdline parameter --- you want to
be passing this to linux. Try:

title Gentoo Xen-linux (2.4.26)
          kernel /xen-20040713.gz dom0_mem=65536 com1=115200,8n1 
          module /bzImage-2.4.26-xen0 root=/dev/hda3 ro console=ttyS0

If you also want console on the vga, I think you can add a
second 'console=tty' option.

This should hopefully get you an oops message dumped to the
serial line if it happens again.
