That does sound like a possibility, but it would impact more than the
wm. I haven't looked at how the panel figures out what width to use, but
my guess is that it asks the Xserver about the root window geometry. 

Since xrandr rotation is quite new for nvidia driver, probably a bug and
the report at the nvidia forum that says that xrandr rotation works in
kde is bogus.
