Yes. General POST support for PPC4xx is available. Could be that the CPU 
specific POST test (like UART, EMAC etc) have to be adapter for 460EX though.

Yes. And IIRC add a small board specific function (post_hotkeys_pressed()). 
You can clone this function from kilauea again.

What peripherals are you referring to? Kilauea has the following POST tests 
defined/enabled by default:

/* POST support */
#define CONFIG_POST             (CONFIG_SYS_POST_CACHE          | \
                                 CONFIG_SYS_POST_CPU            | \
                                 CONFIG_SYS_POST_ETHER          | \
                                 CONFIG_SYS_POST_I2C            | \
                                 CONFIG_SYS_POST_MEMORY | \
                                 CONFIG_SYS_POST_UART)

Again, it's very likely that the UART and/or EMAC tests have to be adapter for 
460EX. I don't think POST has been tested on 460EX before.

Best regards,
Stefan
