Depending on what GPU you have you might consider trying the Nouveau driver.
RandR is reported to be sort of working on NV40 cards. If you want to try
to "hack" on some open driver code to get things working why not the Nouveau
driver? In addition this is what the Nouveau team is working on right now
and I am sure they would not mind additional help.
