Whoops! I actually was generating an error due to a bug. Now that I
fixed it your solution worked, more or less.

For those reading the archive, here's what I did.

First, I took the right hand side of my equation and I used "factorout"
to factor out all the variables not included in the coefficient portion.
So that took my equation and made it look like:

numerator of A * (some stuff)/ denominator of A + numerator of B *
someotherstuff / denominator of B

then I loaded "disol" and asked disolate to isolate the variables that
make up A and B (in this case e and e0). This gave me something like

A * %t123 + B * %t124

then I grabbed the coefficients of each %t variable and boxed them up.
so that I had

box(A) * %t123 + box(B) * %t124

where in fact A and B were rational expressions of e and e0

then when I output my equation via tex, I turned off simplification as
you described and rembox and that gave me more or less what I want.

Thanks!
