Very nice. Of course, it's possible the 6264 is banked in somewhere if you give the right VideoBob register the right poke. Or it could be behind an address/data set of registers like VRAM on the SNES.
ETA; this is about the part where I'd find the boot strings and use IDA Pro's cross-referencer to find the code that prints them
