If the feature is not supported (the kernel is old), the tool will just
return success and the kernel will just ignore max-beb-per1024, which is
not very nice.

It would be better if ubiattach complained like this instead:

ubiattach error: your UBI driver does not allow changing the reserved
                 PEBs count, probably you run old kernel? The support
                 was added in kernel version 3.7.
