If you don't want software rendering for your fonts you have to disable it completly for all types of operations, which means using the VESA driver
I don't follow. VESA was the fastest font-rendering mode across the board for me -- aren't they software-rendered in that mode?

My WAG would be that NV43 offers a feature that NV18 doesn't, and it's getting blindly used, but it's actually slower than the software-only methed. I suppose we could crack open the QT code to see if the feature could be identified.
