For normal small systems, i do not see a requirements for sysfs.
Artifical use case (i don't own HCAs nor euid==0 access to them):
/me builds a well-connected firewall/router/whatever. I don't want
to waste RAM/ROM for sysfs or sysfs support.

I do, however, agree that normal nodes will have sysfs support enabled
in the mid/short run.

As Hal expressed, sysfs is a requirement for OpenIB; so be it.
