safe to set old kernel as default?

["Clea F. Rees" <reescf@gmail.com>]

I'm using Wheezy on my powerbook so the current kernel is 3.0.0.1
which is rather unstable (at least on my machine). The previous kernel
seems to have fewer issues. I do not get the frequent kernel panics.

I was wondering if there is any reason why it would not be good to
change yaboot's configuration so that it boots the old image by
default? I'm wondering if there might be negative side-effects of
setting things up this way which I haven't thought of.

Thanks,
