The drivers do report ECC errors being corrected, which indicates that
the HW itself is doing its job. Yes, I buy cheap memory from eBay.
Do we need actual drivers to output crap on the console? Probably not,
but I'm the wrong person to ask -- I only keep these machines alive to
remind me how things can go horribly wrong.
I don't think there is any harm in keeping this crap around. It
compiles, and if it breaks, I'll fix it. I'm not convinced we need any
more of it though, specially for CPUs that are over a decade old.
