Yeah, if you get a kick out of reverse engineering then it's a plus.
If you don't, then you're better off with something like the BeagleBoard where the TI OMAP3 technical docs, BSP + libraries are all published and have well-supported open source around them.
EDIT: It's worth pointing out that the linked thread is about reverse-engineering the RGB565 graphics mode (for Android) and some of the other esoteric graphics chipset features. Graphics in X11 work fine at the moment, both with Wondermedia's kernel release and with Alexey's open source one. Support for most "normal" WM8505 functions is present in one way or another.
