Kernel Panic after FC4 upgrade

In any case, as I've already posted, I do have the most recent version, so
that's not the issue.
I suppose I could try compiling a custom kernel, but I'm not a kernel
hacker, so I don't have a lot of experience with this, meaning I don't know
for sure what modules I need. And while I understand the concept that's not
terribly likely to be something I could get to work easily. Which is why
I'm really hoping someone can point to something in one of the configuration
files I've posted to date and suggest something else I can try.
Failing that, I'll probably reinstall FC3 and start looking at switching to
Suse...
