The full write up for this can be found on Life Hacker. Basically, you can get the desired results by moving the folder and creating a symlink.

Use your install CD, or you preferred method to get to the recovery console. Firgure our which drive is you SSD and which is your HDD, in this case SSD is E and HDD is D.

Use Robocopy to copy the user directory from the SSD to HDD:

robocopy /copyall /mir /xj E:\Users D:\Users

Remove the users directory on the SSD:

rmdir /S /Q E:\Users

Make a symlink between the old and new location:

mklink /J E:\Users D:\Users

Test by running dir in the root on your SSD, you should see something similar to "Users [D:\Users]"
