The right way to solve this is emulation of hardware cursor offloading.  
The problem is that modern desktops like to use colored cursors and the 
current Cirrus emulation only supports monochromatic cursors :-(

Really no way around this without a special guest driver or new VGA 
emulation.

On the other hand, I had toyed with a shared memory based display 
driver.  That would give you more or less equivalent performance.  
However, I really don't think localhost VNC is that bad.
