Good news that Geminus acceleration will be available on the Iyonix then. The nVidia is capable of a turn of speed and if code is available to make better use of it then all the better.

Short answer - it *won't*, well not in the same way. Caching the bitmaps (even with A9's more limited graphics capabilities) may bring some useful speed improved - if nowhere near as much as with the Iyonix's nVidia. That having been said an improvement is, well, an improvement.
The cache I would think in the case of the A9 would simply be memory space taken out of it's main RAM - whereas on the Iyonix it's on the video card (so you won't be losing precious main RAM just for "caching" bitmaps on the Iyonix).
The take home point is "Geminus" is not a *single* thing - it's different things on different platforms. It's overall effect will be to improve speeds on whatever hardware it runs on.
