About 4k apparently.  See the difference from "400k compressed?".
Also, uncompressing that may add 0.5 second boot time on a slow CPU :-)

I must admit that a solution which makes the effective kernel size
800k larger (your figure) doesn't look like a good standard to me.

If that was the "standard", I'd be tempted to add a MAC address driver
hack to the kernel to save the space :-)
