/dev/sda2 is a default if you are booting from milo and nothing was
specified explicitely or parameters are garbled so you just got lucky.:-)
In particular stuff like 'root = /dev/sda2' is just ignored as syntax is
wrong.  You would get a panic with a root file system on any other
device.

If you have mulitiple kernel parameters with blanks in between then
quote the whole string with "...".

Actually if things are getting more complicated it is much better
to put the whole thing into 'append' line of a corresponding stanza
in your milo.conf.  Like that (an example!):

    .... 
    root=/dev/sda2
    append="cycle=500000000 ro 5"

and whatever else you would like to have there (or things will
become unwieldy pretty fast especially with multiple kernels
and/or different ways to boot).

Type 'cat /proc/cmdline'.  You can also check what is says in
/var/log/dmesg (or do 'dmesg | less' if this is not logged).
