Same problem, down to the 1152 x 864 resolution. I'm using an R300 card as well. Neither Vesa works correcty (low resolution on my 1680 x 1050 monitor) nor does fglrx.
Updates have caused this - the old opens ource drivers when Intrepid FIRST came out worked fine. This is due to a recent update. I'm trying to figure out how to revert to the initial install.
