I'm in the process of upgrading a Debian box to Squeeze, and on startup

Nothing written to /var/log/dmesg at all. C-s/C-q no help. Is there a
way of stepping though or paging a startup?
I don't know of any way of doing that. However, if you have another
computer you could set it up as a serial console. Alternatively, if you
have a parallel port printer around that prints plain text there is also
a parallel console option.
For serial console, add e.g.:
console=tty0 console=ttyS0,38400n8
For parallel console, add:
console=tty0 console=lp0
...to the kernel command line.
That's great - serial I/O would be perfect.
I see that Grub also has nice features to use serial too:

(likely to be a bit dated).
