Well, we've just been dumb here. There are IDE drive cables that have pin 20 covered to stop them being put in upside-down. Well, we've gone and done just that (don't ask how, I can't even figure that one out right now), and while the drive appears to still be working I'd really appreciate it if someone knows where to find a list of what pin does what on a standard 40-pin IDE interface. I dread to think what we've just broken.
doh!

And the answer is that the DMA request pin is dead. Fortunately, Linux has defaulted over to using PIO mode, and the data is coming off it nicely now. So while the disk is a bid dead its not a data loss situation (its backed up anyway, but restoring its a pain).

Well, asking the forum seemed like a good at time...
Still, at least people now know what happens when you're an idiot.

I did that once (why do so many HDD cables not have the polarisation tab, but do have the faintest pin1 stripe? Do they think we all install it in perfect lighting conditions?!!) but my drive was fine n dandy afterwards

I can't count the number of times I've asked a question in a forum, IRC or IRL only to find the answer myself minutes or even seconds later. Sometimes it's the best way to figure stuff out yourself.
