Xsp extension exists and works for 770, N800 and N810.

By using Xsp and an 8-bit SDL surface, you can get 60fps screen updates. Software scaling through sdl will be lower than that, as will higher bpp SDL surfaces.

There exist other options for faster screen updates, but these are also 'device specific'. While I understand that blachner is working on the main cvs tree and does not want to pollute it with device-specific hacks, I do not see this as a valid reason to reject Xsp for tablet builds of Frodo. Indeed I do not see an alternative.

Thanks for working on this
Cheers,
