This will never work. I bet it didn't work with your old kernel
either. 0x10000 is just 64 kB - this is _never_ enough for an
uncompressed Linux kernel. You will overwrite your kernel while
uncompressing it, which crashes the system. Use a higher load address, somthing like 0x200000.

You have to _unset_ clocks_in_mhz for a 2.4.20-pre2 kernel.

Well, it's not _that_ difficult. Try it out, so you get used to is ;-)

Just open your eyes, and thou shalt see :-)

Always leave room to add an explanation if it doesn't work out.
