@atmasphere, it wont. The OMAP3 gives you that 2-3x performance for the same power consumption figures as the OMAP2.
There's a neat little concept with ARM processors called "race-to-idle". At idle, ARM CPUs use practically zero power (in the case of the Cortex A8 in the OMAP3, that's actually zero power), so you want to get to idle as quickly as possible.
Basically, given two CPUs (in this case, an ARM11 and a Cortex A8) both working on the same task (say, encoding a 60 second audio file into MP3) and assuming similar power consumption at 100% CPU usage (400MHz for the ARM11 and 600MHz for the Cortex A8) the faster CPU will use significantly less power, because it takes less time to complete the task and will get to idle (and thus stop using power) much more quickly.
This is why (as counter-intuitive as it may sound), it's actually more battery-friendly (for normal usage, anyway) to ramp the CPU up to its maximum clock rate rather than limiting it to a lower MHz, as it'll get done with the task more quickly and can switch itself off.
That said, peak consumption for the OMAP3 is going to be a little bit higher than the OMAP2. Mostly because we're actually using the PowerVR this time around. So expect somewhat shorter battery life with the RX-51 when you're playing Quake 3 over 3G and listening to your favorite podcasts. ;)

@bogart, the problem with that comparison is that the N800 and the N810 are almost exactly the same tablet (on the inside, where it counts) support for the N800 is essentially provided for free when you build support for the N810. All you have to do is make sure virtual input methods are supported and don't assume the availability of GPS, a hardware keyboard, or 2GB of built-in storage and you're done. ;)
Now, the differences between the N8x0, which use OMAP2, and the "N900" (RX-51), which uses OMAP3, are more profound than even the differences between the 770 and the N8x0.
Considering only the CPU, there's a 2-3x performance increase with the OMAP3 tablet over the OMAP2 tablets. When you factor in things like the HD camera, cellular connectivity, and OpenGL, it's really, truly, a whole different ball game.
@atmasphere, if you're looking for N8x0 support, you're probably going to want to pay attention to Mer once we get a few months down the road (think beta SDK timeframe).

Don't really see the need. Traffic isn't all that heavy in #maemo, so it's not really a load issue, and it seems to me that segregating out the normals users will probably result in them getting less help.
