I did not get to the karmic kernel, but have now done the current Jaunty 
against a version including the picked set of patches. Both had two tests 
failing (213, 214). Strangely those seem to be tests that look like only useful 
for xfs. Also in theory they seem to be requiring the fallocate command which 
is not included in the tools. So I guess that is a rather a problem with the 
test than one with the fs.
So at least it seems to assure, that applying the patches does not make things 
worse (aka causes regressions).
