uhm, you should not need to modify the initrd scripts by hand to make it
do what you need, (and mdk-9.2 initrd should not load raid modules if it
does not need it to boot, but this i already fixed).
having a correct scsi_hostadapter line in /etc/modules_conf should deal
with loading the firewire module before, or you could use --preload
<module> argument.
i don't have firewire hw to test this, and i'll never buy an usb drive
if i can avoid it :-)
would you be willing to test the alternative mkinitrd/initscripts/mdadm
packages i built for mandrake cooker and report success/failure on your
configuration?
they are found at: http://www.comedia.it/~bluca/cooker/lvm2/
