This is the first time I have ever heard of it. I had assumed that
your problem was that you were building your own kernel, so the KEXT
cache was out of date relative to the kernel, and the driver could not
be loaded by the boot loader from the cache (it didn't match the
kernel), and without a PCI driver, you couldn't load the PCI driver
off disk.

Thanks again, Terry. I tried the rebuild and the complaint was that
there was not a usr/../bootcache.plist (or something to that
effect). Can't imagine how that could have happened, since I was
not aware of that file. So I thought doing an 'upgrade' from an
Install DVD would solve the problem. No way. The upgrade finished
normally, but there was neither the bootcache.plist nor the
kextentions.cache (sp?) files. This is confusing, as I expect a
system upgrade to make all the necessary files to do a normal
startup. I will locate an active bootcache.plist from an existing
system partition and copy it to the usr/../ directory to see if it
will help me do the kextcache rebuild. Do you think this is an
anomaly for me or has this happened many times before and I should
file a radar report?

You need to rebuild the KEXT cache, not the KEXT.

Thanks, Terry. I'll rebuild the KEXT. But forgot how at the
moment. Any hints?

This is a new one for me: G5 complains about
'com.apple.driver.AppleMacRiscPCI' missing in the startup from
'kld_load_from_memory()'. I got that using <cmd-V> at startup.
I used another system partition to look it the file was there
(in System/Library/Extensions/) and it was! So I took out the
kextensions.cache and its partner and tried again: still got the
same complaint. (By the way, it says there are 1310 buffer
headers and 1310 cluster IO buffer header, if that matters.)
Do anyone know of something else to try? This is under OSX
10.4.10 as well as 10.4.2 (which I reloaded in hopes of clearing
up "lost" files).
Instead of removing the KEXT cache, rebuild it.
The error is indicating that it's unable to load it from the
cache that was loaded into memory by the boot loader.
It can't read it off the disk itself because it can't even talk
to the PCI bus on which the disk controller lives without this
KEXT loaded.
