hmm. the fusion mpt driver resides in a different location
(/lib/modules/$(uname -r)/kernel/drivers/message/fusion) so you have to add
this directory to the 'find'. but then again, the simple dependency logic
does not work here because there are multiple dependencies and modinfo prints
them in random order (for mptsas.ko to load you need to load mptbase.ko and
mptscsih.ko in this order). modprobe would be cool here ... any reason not to
use it?

this sounds good. recent kernel/initramfs combinations are really powerful and
flexible regarding the device of the root filesystem. for which release is
the live-initramfs transition planned?
cheers bzw. sers,
