oh boy, next time better email me directly please, it's only by luck that i caught this in rss ;). as for the patches, i did submit them last year to the cfe-dev list, only a few things changed since. if you're in a hurry for an up-to-date version (against linux 3.3.1) then email me please (lwn doesn't reveal your email address).
one of these days i'd also like to post an update now that llvm/clang 3.1 is nearing completion, i just have to finish my default argument support patch for asm macros so that we may then be able to use integrated-as for linux.
