I realise that the reason that Linux will not boot is due to the CMOS setting of the graphics card shared aperture now being 8MB rather than the old 2MB. For some reason Linux doesn't detect the amount of memory on the motherboard (over 64MB) and so I had to hardwire it.
The ethernet card still works (hooray). It appears that the video capture card is dead -- or maybe the camera is fried.
It turns out that the video cable is not connected to the capture card -- I disconnected it when I was trying to figure out what was broken. Reconnecting the cable fixes that.
The temperature and rain gauge sensors are not operational -- the instrumentation bus does not detect the presence of any devices. Having said that, it also doesn't detect the presence of a shorted out bus, so I suspect that the interface dongle may be fried.
I now have surge suppressors for the video wiring and the instrumentation bus wiring.
