2. The start address is fixed to 0x0
One "start" address that is not fixed is the initial load
address. Where the

worry about
this if you are using one of the available boot loaders.
Sorry, should NOT have to worry about that address...
Wrong, you SHOULD worry about this address. Load the kernel to a  low
enough  address  (say  at  0x10000)  and  the uncompressing code will
probably overwrite the kernel image.

The point is if you are using one of the available boot loaders, it normally
takes care of loading and decompressing the kernel. If you have the urge to
experiment with the load address, then you are right. Normally this is
out-of-sight, out-of-mind.
