It does for me..

I can't quite parse that -- Does nothing show up until after getty starts
(e.g., no boot messages) or does nothing show up after getty starts (e.g.,
no login prompt).
Also, what OS? I'm using FreeBSD 4.6-STABLE. In case you are the same,
things to try include:
1. Make sure you turn on the console line in /etc/ttys:
console "/usr/libexec/getty std.19200" vt100 on secure
(std.19200 may need to change to std.9600 depending on your Soekris BIOS
2. Set your console speed in your kernel:
options CONSPEED=19200 # Console speed
3. Make sure you serial port is set as a console device in your kernel:
device sio0 at isa? port IO_COM1 flags 0x30 irq 4
The flags setting is described in the sio man page.
