From what I see, the boards look fine. The bubbled solder plate under the solder mask on the bottom side of the board was not unusual. The Bitstreamer is the original version of their later Bistreamer II board, but from what I can tell in the pictures, the jumpers you’re seeing are just for setting the address of the board and for configuring serial I/O.
I’d say the first step is to get the CPU to jump into the monitor in EPROM and see the monitor initialize the screen and put up the command prompt. Try this with just the CPU, PROM/RAM, and FlashWriter cards installed. If this works, then one of the cards you pulled out is causing a problem. If you still don’t get a good startup screen (most likely), then check the output voltage of each regulator on the CPU card and PROM/RAM card and let me know what you measure.
