Two options in Eagle:
First, try turning off the top and autorouting everything on the
bottom. When you click the autoroute button, the window that pops up
allows you to choose which direction to route each layer, or you can
turn a layer off by selecting "N/A". If you've got just one or two
wires that didn't route, you can make jumpers. (Or run traces yourself
on the top layer, with vias to pass the signal through.)
Second, check out the following ULPS. (I cut and pasted from Cadsoft's
Download
page for ULPs.) One of them might work for you.
restrict-4.03.ulp 3,854 5,721 Tue Nov 6 03:38:52 2001
A modified version of restrict.ulp. This restrict.ulp accurately
restrict pads according to pad type. Purpose of this script is to restrict
top component pads to be included in the double sided Autorouting.

restrict.ulp 2,745 6,927 Fri Mar 9 02:11:30 2001
This ULP puts RECTs on the 'tRestrict' layer around all the pads. You
may want this if you want to make a double-sided board, but only want to
solder on the bottom layer.
This ULP is only a slight adaptation from the obsolete '0V_restr.ulp'.
It now runs in Eagle 4.01 and includes all connected pads.

I just realized something...
How can I solder a two-sided board if I'm using sockets for the
IC's? Ugh!
And some of the traces ∗can∗ be moved to the bottom, but Eagle is
routing them on top.
