I will do so and edit it into my last post for convenience.
And I have since changed the setup described in the original post, though the issue with X not starting remains.
My idea originally was that this computer could serve as a really basic desktop for browsing, email, etc; having it start to simply a browser seemed the best way to get the most out of it, and for the most part, it is usable for the most part, as long as flash isn't involved obviously.
When that didn't work, as I hinted at but wasn't clear about earlier, I fully reinstalled, full tinycore, which booted properly the first time, and then the same issue as here. I no longer have chromium in .X.d, and have actually switched to seamonkey.
More relevantly, possibly, I also switched flwm_topside to openbox a few hours ago, as my xorg log will most likely show, but otherwise, no changes between the two logs
