I do. All the time.

You need a Linux kernel that is compiled with serial console support.
And to enable that you need to pass the parameter "console=ttyS0,9600"
to the kernel too.

You will not get any output from the BIOS or from the bzImage-bootloader
though, they seem to write directly to the VGA hardware. And I am not
sure if Ctrl-Alt-1/2/3 works correctly - I do however get a monitor
prompt displayed the first thing... wierd.

I do no not think the -nographic option disables emulation of VGA
hardware, though.  An option for that might be useful for embedded
programmers.
