Put your maps onto an SD card instead

This is a bit of a blue-sky idea. Technically really difficult, but I'm thinking about it anyway.

I want to rip out the CD/DVD drive and replace it with an SD card reader. No more scratched disks, moving parts inside your boot, slow seek/access times etc.

Would there be any interest in buying such a unit if I made a few?

The technical problems:

1) I can't figure out the pinout of the CD/DVD socket. It's 50 pins and the following appear to be grounded: 2,19,21,23,25,28,38,40,42,44. It looks suspiciously like 40-pin IDE, but with some head scratching differences. Help!

2) Emulating an ATAPI CD-rom by bit banging would require a _really_ fast microcontroller.
