Yes, that 's what OFED uses for userspace.

So, I guess you want to just remove the rest of the stuff?

We can try looking into that. So what do you want it to include?
We currently only target RPM based distros.
Are you willing to maintan the gentoo support?
Maybe after each release candidate you can prepare the tarball
for gentoo and upload it?

That's fine too, I think.

Hmm. Which kernel do you run?
If you have 2.6.18, it's easy to add just SDP as an out of kernel module.
