My point was that there are now 2 different mechanisms - one or maybe both
can be used with something like GAMMA. The introduction _in a stable
kernel_ of a second such interface was a mistake IMHO. Especially if, as
you say, this is the one that will stay. So people trying to implement
something to plug in the kernel are forced to change their minds if they
picked the wrong interface - which is always difficult, especially when
this is open-source and commitment is at own will. So, apart from
supporting the ever changing hardware, they have to support the ever
changing software as well ! Of course that this will discourage anybody
and that's why I thought that involvment of a company/university/other
insitution would motivate more the developers.
