Thanks.

Even I do not really see the necessity. I do in no way want to criticize your work, but:
We have 1G of mem, from which 256M is reserved for ramzwap (swap usage). So if you not have heavily modded your device, lots of daemons running and/or tons of apps open at the same time, this should not make the device any faster.
And I do not know of any problems with swap fragmentation (as on te N900, need to defrag/re-swap).

Out of curiosity: where do you gain the additional swap space from? Increasing ramzwap (hereby decreasing real RAM) would not make sense. Or from "unused" mtd5? In latter case you should give a hint/warning (at least to 'old-style' ubiboot users) about using that device.
