I had many of those errors. May be the pins of the mem modules are corroded. But often I found that
the solder pads itself were broken that means the soldering points are disconnected or at least
"cold". Use your finger nail to check if some of the solder pins got loose.

This is very likely that the solder pads got "cold".

To correct this get a soldering iron. Be careful to groud yourself. The mem modules are picky about
electrostatic charge. And then solder the pads again. This way I refurbished some 128MB of 32MB mem
boards (MS02-CA).

loopback ?? This usually shows up, if the AUI port has no receiver and there is no cable connecting
this to some other port. At least there should be a loopback plugged in.

I run 1.5.2 like a charm. Its solid as a rock.
