Translation: you purchased hardware which requires binary-only kernel
modules to provide needed functionality.

No, it shows us a main problem of Compaq high-availability storage
products in a Linux environment. If you're going to point fingers,
make sure they're pointed the right direction.

I'm not sure how the linux-kernel list is supposed to help you. The
development model of open-source drivers and source-only compatibility
(even that being broken from time to time) is well-established. It's
not going to change. And Compaq is fully aware of it. They have
chosen to swim against the current, providing themselves (and
occasionally their customers, as you have seen) with considerable
headaches as a result. If they are unable to produce high-quality
drivers for the kernels you wish to run, or at least for a list of
kernels they explicitly support, there are other datacenter storage
vendors (and indeed other operating systems) out there. IBM for
instance makes all the right noises - maybe they have products you can
use.
