The large vmlinux size deltas are due to the OMAP2+ shift from uImage builds to zImage builds. The script here doesn't track size differences across kernel build formats, so to that script, it appears that the builds just started working.

Full-chip power management for OMAP3 is now clearly broken. Folks who need that for their application should use older kernels. Recollection is foggy but v3.7 should be pretty good for OMAP3; the clock code & data in that one is a bit more mature.

The good news is that the 4460 VAR-SOM-OM is now booting again. Removed the LCD board, which got rid of the noise on the serial line - must have been leaking through from the inverter. Also switched serial interfaces. Clearly this needs a bit more investigation.

Looks like the kernel runtime memory bloat trend has resumed.
