Sure, yes, the crash utility can always support another dumpfile format.

It's unclear to me how similar SADUMP is to diskdump/compressed-kdump.
Does your internal version patch diskdump.c, or do you maintain your
own "sadump.c"?  I ask because if your patchset is at all intrusive,
I'd prefer it be kept in its own file, primarily for maintainability,
but also because SADUMP is essentially a black-box to anybody outside
Fujitsu.
