Tried something like device scsi aic7xxx --opts=verbose in ks.cfg, but this option did not make it into modules.conf (neither anaconda's or the one in sysimage).
We read the kickstart config after the module is loaded so there's not a lot we can do. Have some ideas on how to move things around written on a sheet of paper beside my desk that I should dump here instead :)
Added a nonet and nostorage option so that you can load needed devices with options via your ks.cfg.
