Replacing the microdrive in a Sharp Zaurus

I have a Sharp SL-C3100 clamshell Zaurus (also known as a spitz), which has a 4GB Hitachi Microdrive in it.

Although I think Microdrives are nifty, they have problems:

they use more power than NAND flash
they have higher latency
they have lower throughput
they don't have the shock resilience of a solid state device

So I replaced the 4GiB Microdrive with an 8GiB NAND flash card.

Issues that I ran into

all of the internal PCBs need to be separated to get at the CF slot where the microdrive is.
the linux kernel needs to be patched with the manufid, and prodid of the card, so that the new device can be used for the root filesystem (otherwise you'll get a kernel panic on boot)

Here's the patch
