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,
