Debian install over Serial redux

[debian@halligan.org]

I thought I had it booting, but I was looking at the wrong serial
console..


Here's what I've tried : 

- Booting sarge's netinstaller over PXE without kernel append options,
hoping it'd just pick it up.
- Booting with "console=tty0"
- Booting with "console=ttyS0"
- Booting with "console=ttyS0,9600n8"
- Booting with "console=ttyS0,9600n8"
- Booting with "console=ttyS0,9600n8 debian-installer/framebuffer=false"
- Booting with "console=ttyS0,9600n8 debian-installer/framebuffer=false debconf/frontend=text"
- Booting with "console=ttyS0,9600n8 debian-installer/framebuffer=false debconf/frontend=text video=vg16:off"
- Booting with "console=ttyS0,9600n8 debian-installer/framebuffer=false
  debconf/frontend=ncurses video=vg16:off"
- editing  the cdebconf.conf file in the ramdisk and changing the
  default from  newt to text.

Still,  Asoon as the kernel gets to the serial driver loading, I get
some kind of multi-byte character output that looks like this : 
Serial: 8250/16550 driver $Revision: 1.90 $ 54 ports, IRQ sharing
enabled

Any thoughts on this one?
