 That might explain why Mark does not see panics (assuming the NFS
 client code has had more testing on sparc64 or similar architectures
 which does not seem unlikely (e.g. in the build cluster))...

 Your patch applies more or less cleanly (a line or two offset here and
 there, but nothing to worry about AFAICT), and make buildkernel is having
 a go at the sources. I'll let you know what comes out.
