Hmm.. all of my files in the dd image look correct.

In addition to the files above, I also have "pci.ids" file. 
FC5 installer will give 
"ERROR failed to open /tmp/drivers/pci.ids: No such file or directory" 
error if I don't have that file on the dd image.

"pci.ids", "pcitable" and "modules.pcimap" contain correct pci/device ids
(verified with lspci - and those files are taken from "official" qlogic rhel4 
qla4xxx dd image)

fs of the dd image is vfat. FC5 installer didn't seem to like ext2.

Hmm.. that i586 module seems to be a lot bigger than the i686 versions.. 
i586 version is compiled by hand, i686 versions are compiled automatically
by ddiskit.

But anyway, FC5 installer doesn't like this image. It starts to read the
floppy ("Reading driver disk"), but it won't load the module. No errors in the VC3. 

In VC3 I see only this: 
"INFO  trying to mount sdb"
"INFO  modules to insert"
"INFO  load module set done"

When I manually extract the i586 qla4xxx.ko from the dd image, I can load it
fine with insmod..

Any ideas? For some reason the installer doesn't even try to load the
qla4xxx module..
