You've interpreted the disclaimer wrong -- "if you want my patches
upstream do it yourself or pay for it cause I have neither time nor
interest in an added bureaucracy and clean-yet-buggy mentality"..

Lets put things in the right perspective, look at your pull request:

48 files changed, 663 insertions(+), 417 deletions(-)

then at Dave's IDE pull request:

52 files changed, 617 insertions(+), 678 deletions(-)

and finally at my atang tree (I'm just testing 2.6.33 rebase):

328 files changed, 11528 insertions(+), 14491 deletions(-)

This is a whole different scale of changes and you shouldn't be
surprised that it requires a bit different set of strategies to
handle it effectively..
