I realize that 1024 seems large enough for a traditional OS. In my Java Virtual Machine guest, I am faced with some applications that issue very large command lines, certainly in excess of 1024. There are workarounds, but it means I can't run certain apps out of the box.
The initial ram disk is just an 'module' you can load into guest memory for
interpretation by the guest kernel as it loads. Convention is to load it
