Other suggestion which came about was to parse the kernel command line and look for "elfcorehdr=". Is this ok? Is kernel command line visible to the SCSI drivers?

Perhaps you should be automatically using little resources when little memory is available, or something? With upcomping kjump patches, it is more "interesting" than kdump vs. no kdump.
