I have 2 spare nodes so i'll run both. 1) is on already without any issues
i'm just compiling 2)

I usually work on -mm, so what would be interesting for me is to have what you 
need in net-2.6.24 which is getting pulled in -mm by andrew. then, if you need 
an extra patch for verbosity, that's fine, i'll include it in my usual patchset.

Cheers,
