IMHO you need
        - An understanding of ATA (which is the protocol
                equivalent of object oriented cobol)
        - The ability to work with vendors (it needs to be someone
                at a company because many vendors won't NDA with
                individuals even if they are happy with GPL code off
                their data sheet)
        - Someone who has taste in code and understands how to
                beat code into shape without breaking it
        - The ability to deduce the other errata the vendor forgot
                to tell you about or doesn't want to admit exists for
                fear of US lawsuits (I kid you not)
        - A good understanding of the block layer and its locking
                especially because IDE has a heirarchy of contention
                        two drives one bus
                        two channels one DMA engine
                        two controllers one I/O at a time
                        ISA IRQ sharing locks
