    What is the bootrom? Is it a piece of hardware? Is it part of the firmware? (I don't think it is) Is it some software contained on a separate flash memory thing?

    The bootrom is the thing that boots the system. Oh, and it is not touched by a firmware update. Thats all I know.

    The BootROM is an actual microchip...the data in it is physically burned onto the chip so it can never be edited/flashed etc.

    The bootrom is a physical chip that the iDevice uses to boot. Every different model that comes out has a different chip than the other models, so you can't take, say, a 2G chip and put it in a 3G. Also, the information is burned into the chip, so it cannot be modified in any way, software, or hardware. It is also the basis for everything that boots after that, i.e. iBoot, LLB, etc. Therefore, it allows the unsigned code that the jailbreaks need to be run everywhere. For more info, go to the iPhone wiki.
