Update...

I added serpentines to the short traces, and re-routed the long traces
to go under the sdram chip instead of around it, and got the
following...  Only 381 mils difference between the shortest and
longest.  http://www.delorie.com/electronics/sdram/

Net     R_WE    length  1.509   in
Net     R_RAS   length  1.519   in
Net     R_CAS   length  1.539   in
Net     R_DQML  length  1.554   in
Net     R_A10   length  1.586   in
Net     R_BA1   length  1.586   in

Net     R_A3    length  1.600   in
Net     R_DQ2   length  1.614   in
Net     R_DQ5   length  1.614   in
Net     R_A1    length  1.615   in
Net     R_BA0   length  1.615   in
Net     R_A11   length  1.620   in
Net     R_A2    length  1.620   in
Net     R_DQ1   length  1.625   in
Net     R_DQ4   length  1.627   in
Net     R_CS    length  1.657   in
Net     R_CKE   length  1.666   in
Net     R_DQ7   length  1.675   in
Net     R_DQ6   length  1.695   in
Net     R_A9    length  1.729   in
Net     R_A8    length  1.742   in
Net     R_A7    length  1.762   in
Net     R_A6    length  1.775   in
Net     R_A5    length  1.795   in
Net     R_DQ8   length  1.798   in
Net     R_A4    length  1.826   in
Net     R_DQ13  length  1.852   in
Net     R_DQ11  length  1.855   in
Net     R_DQ9   length  1.857   in
Net     R_DQ12  length  1.867   in
Net     R_DQ10  length  1.869   in
Net     R_DQMH  length  1.879   in
Net     R_DQ14  length  1.883   in
Net     R_DQ15  length  1.886   in
Net     R_CLK   length  1.890   in

And yes, I added a command to show the length of all nets.
Report(AllNetLengths).  I also used a script to remove the logic
analyzer traces from the above report, and pull out the nets I wanted.
