You need hotplug working to do what you are trying to do with the camera.  So 
nothing will work on that front until you have hotplug happy again.

I don't know what these modules do, but I think you can get around the errors 
by adding

install ide-probe /bin/true
install ide-probe-mod /bin/true

in /etc/modprobe.conf.

Actually, that might not be the best advice, read on.

This looks bad.  USB storage devices pretend to be SCSI.  It looks like your 
kernel config does not have [some kind of] SCSI support selected as a module.  
Possibly your config lacks some kind of IDE support as a module too, which 
would explain the other errors.

You have two choices as I see it.  First, instead of using a random "Gene" 
kernel config, use the one from Redhat.  If you look inside a Redhat 2.6 
kernel RPM, you will see a /boot/config-<version> file which is the 
kernel .config that the Redhat kernel was compiled with.  Copy this to 
be .config in your kernel tree and make oldconfig (I think that will do).

Second, why do you need a custom kernel?  Why not use a Redhat RPM-packaged 
one.  All this pain will just go away.  New pain may come, but less than this 
toothache.
