Hi again,

I got no comments -- doesn't matter :-)
Anyway, I hacked Milo to load the kernel file with a single
read() call, and what shall I say...

Kernel load time for 728019 bytes on my Magnum 4000:

before: 300 seconds
after:   26 seconds

and Milo is some kbytes smaller now, too.

To the ELF hackers: elf_open_kernel() isn't necessary
anymore. You just need to write elf_load_kernel the
same way as aout_load_kernel() now works:

- get kernel filesize
- malloc filesize bytes
- read complete file
- copy exec header into struct kexec
- set pointer to symbols
- return pointer to kernel text

That's it.
