Uhm, please read the error message. It doesn't say modules are disabled, it
says there's no such file as /proc/config.gz. Which is pointless in most
cases, and thus is not present on any of Ben Hutchings' kernels (ie, those
shipped by Debian and Devuan), nor in those I build myself.

Standard Debian/Devuan kernels do ship zram as a module.

I would recommend against using random kernels from outside sources unless
you know what you're doing. Debian/Devuan kernels are configured to support
an enormous number of setups, and this, unlike optimizing for a particular
machine/task is not easy to do right.

Usually getting a reasonable kernel configuration is not rocket surgery, but
you need to know the basics.
