The r200 driver doesn't support ARB_pbo. This needs the texmem / ttm work Thomas has commited recently, but the only (open source) dri driver currently supporting it is i915. There's a whole bunch of stuff which would get faster a lot when the driver is adapted (like CopyTexSubImage which is really needed for doom3:roe).
