....  Although I have now
coaxed 2.3.18 as far as trying to load the initrd, it has been an uphill
struggle all the way and I still haven't got the compressed bootloader
going properly.  Could it be that my problems stem from using 2.3.18?

As I recall, the ram disk didn't work in 2.3.18.  There are some
general things that don't work in 2.3.18, so I bailed out and
updated 2.2.xx to get something stable.  Since 2.3.xx is now
in it's mid-30's (still younger than I :-), perhaps it is mature
enough that I should visit again and make sure the 8xx configuration
continues to work.

Speaking of updating and 2.2, 8xx support were broken in 2.2.14 because
of changes in kernel/head.S. Could someone take care so that the
following patch makes it into 2.2.15:

Also, is there any reason why not at least the 8xx-only code in 2.2.15
could be updated to working versions?
