In the special case of linux-2.6 that might be a bug. But how will 3.0
(quilt) format then work? So it doesn't go and do something crazy
anymore. Instead it fails. That is not working. And I there were more
examples in the thread like e.g. wesnoth.

If it works it is luck. It only works if the patch system does not
pick up any of the dpkg files and dpkg does not pick up any of the
patch systems files. Which generaly is not the case. Gnerally you have
to do some work to make sure nothing conflicts or to make it not
conflict.
Esspecially the case where the packages patch system is quilt is
tricky as it works if dpkg uses quilt (if quilt is installed before
dpkg-source is called) but not if quilt is pulled in later through
Build-Depends.
So while you can make the two work side by side, if you seperate them
enough, I stand by what I wrote for the general case. Blindly mixing
patch systems spells disaster. The advertising makes it sound like it
will magcially always work.
