Reverse engineering binary firmware

 e100 might be a simpler task, and nearly as useful: there's some
 indication in the driver that the processor that runs the microcode is
 8086, the microcode snippets are small (limited to 134 32-bit words),
 and a very large number of Intel chipsets are bundled with network
 interfaces that require this microcode.

 Another more challenging piece of firwmare is that for Broadcom Everest
 network cards, bnx2x driver. It's a pretty large, often-changing chunk
 of (IIRC MIPS-targeted) management firmware. I have no idea of how
 widely deployed it is.
