You probably also want them aligned to 256Kbyte after or similar so that you can drop the initrd into a seperate erase block on the flash. There are people doing this. Its actually not hard to hardwire an address into the initrd code. Red Boot knows how to do this nicely and it may be a good approach. It does all the work for this on the ipaq for example. You can also run some kernels out of flash, I've helped someone get the x86 kernels running from flash for example.
