OK, so I later realized that since I own VMWare Fusion for some office XP apps, I could create an Ubuntu virtual machine. So ultimately I caved in, installed, config'd, etc. Ubuntu under Fusion and used it to flash NITdroid. I never did get adb to work right -- kept saying it couldn't find the device, but the 0.4.0 filesystem seemed to already have the mappings in it as the hardware keyboard worked fine without manually pushing the layout. Pretty impressive work, if only the power button and keylock (screenlock) was functional, I might have stayed booted in it longer.
