I updated the AmiMPC web with details of a new head unit I have been working on, which is greatly improved over the old one. See the web site for more info. My new head unit looks almost factory, and features a digital potentiometer based volume control. I think I'm finally 100% happy with the system!See the AmiMPC website for more details.

Nice plasticwork!
Obviously this is a hobby project, and a bit impractical for those of us not swimming in 1200s. That's not going to keep me from asking annoying questions, so here they are- don't take them as criticism. :) [I have deja-vu, so perhaps I said some of this before..]
Where does the dependence on the 030 come in? Is hitting the parallel port like that just too intense to play nicely with the disk accesses, especially with any additional polling loops for the controls?
As to the buffering- it'll protect from system latencies, but what occurs if the drive gives up on its own remapping algorithms and turns up a bad sector (you're using IDE, so I don't think you get to tune for retry-or-bust the way modern SCSI drives' mode pages would allow)? What's curious about the iPod is that Apple seems to have really engineered shock resistance into the system; one of the early 'look what we gutted!' pages noted that its little HD could be munged by pressing too hard on the lid, but that playback would resume afterwards. (I assume that would've caused a bit more damage than even a good HD could remap around; perhaps they have a mechanism to 'fill in' lost sectors from the buffer?)
Of course, now I'm thinking about alternative implementations...
