Just to follow up to my own posting. I've found that in my linux-2.4.18
kernel, there is a file arch/ppc/platforms/evb405ep.h which does include a
board_info struct which is quite a bit different from the struct in
u-boot.h. I've made those match and re-built the kernel, still with no luck.

I've re-built U-Boot in debug mode so I can see what is going on. Here's
what it spits out before the board locks up:

=> iminfo 500000

Any ideas?
