I don't think that's right.  I'm running 1600x1200, with an ATI Radeon 
X300 (RV370) 5B60 PCIE, a Dell monitor flat panel, a DVI cable, and xorg
from pkgsrc.  (XFree86 wouldn't do it.)  If I'm reading the log 
correctly, it's running at 162 Mhz.  The configuration is just what was 
generated by Xorg.
