ah ok.

Assuming it's ok that the modules won't always be present - i.e. they're
only built on powerpc - the modules will be:

nx-compress
nx-compress-crypto
nx-compress-platform
nx-compress-pseries
nx-compress-powernv
842-decompress

the 842-compress module actually isn't needed; the 842-compress and
842-decompress modules are only the "reference implementation" in
software, and due to the specifics of the 842 format they are very
painfully slow; 842 is really only suited to be done in custom hardware.

The 842-decompress module is needed, because the 842 hardware driver
falls back to using it if the hardware fails or is disabled, so that
decompression never fails.

but including the 842-compress module doesn't hurt anything.
