dunno which forum/review did u read...but according to AnandTech, quoted:
"..The discovery that the Ultra chipset can be easily modded to SLI removes a major obstacle to SLI performance on the cheaper Ultra boards - if the manufacturer made provisions for SLI. Once the SLI mod is complete, the system and nVidia drivers see the chipset as a full SLI chipset.
This removes the driver issues and the ability of nVidia to turn off support in "non-complying Ultra SLI chipsets".
or click
here!no more prob with the driver. u can even use the new driver...just connect one part and walla...u have 'SLI-modded" board...
havent try on mine thou...actually, i still waiting for my hsf b4 setup my nf4 system.

quite agree with what you said
because since ultra chip can be modded to SLi, it mean that ultra chip is almost same with the SLi chip or totally same with some hidden feature,
i think even new driver won't be able to detect which one is modded or which one is SLi , unless the mod isn't 100% complete
else, driver shouldn;t a problem rite ?
