Sweet!

Can anybody confirm XO Laptops' "1200x900" resolution gets converted 
cleanly to "640x480" when projected from Sugar?

For example, can the Binaries here at 
http://wiki.laptop.org/go/Adding_USB_SVGA#Binaries help any teacher fire 
up her/his class without much hassle?
(In this case, on OLPC Software Release 8.2.1 = Build 802 = Sugar 0.82)
