A mouse user will eventually find the button on the left if it's not

Eventually doesn't seem to be a winning model to me.
Now, unless you have a majority of keyboard savvy users, then I'd
still opt for a model that works well for both, not "eventually" for
the majority.
Design for the 80%. So, unless 80% of your users are keyboard-based
users, then you're best bet is "Previous" left and "Next" right. Even
if you have a high degree of keyboard-based users, then using tab
order, as others have pointed out, combined with making the default
action (e.g. Next) the form submit action, you're in the best of both
worlds.
As far as having them next to each other, or one on the far right and
one on the far left, we'll we've studied both and haven't seen a
significant difference or advantage. We've seen theoretical
differences and advantages, but in actual use, we haven't found a
significant difference.

In theory, theory and practice are the same.
In practice, they are not.
