Cool, merged into next/soc now. Is the kernel about to outgrow these platforms due to binary size just slowly increasing over time, or is it still usable?

Hi,

It's still very much usable. On currently actively tested OMAP1 boards we have >= 32 MB RAM, and there hasn't been any issues. You might need a custom kconfig however, depending on which board you are using.

On Nokia 770, the bootloader refuses > 2 MB kernel, so I'm using chainloading (still with a modern kernel, but with minimized .config) and kexec to boot a bigger kernel. But this has been going on for couple of years already.
