Re: newbie kernel compilation problems: mtd_pm_callback undefined

First, I'd recommend using 3.4.3, as that's what we're using to compile.

Second, I accidentally checked in an incomplete patch in hx4700_core.c.
You can comment out the calls to mtd_pm_callback for the immediate solution.

I've just updated the default config, as well. Hope this helps.
