BTW: m68k, not m86k... a common typo ;)

There definitely add-on cards that can make full use of advanced audio, e.g. 
the Toccata Zorro-II card for Amigas.

It is available, I think... at least on Ebay, but I can only speak for
Amigas, and as Christian Brandt already replied, there *are* some cards out
there, but I don't know if there used that much under Linux.

So I don't want to either. Therefore we should wait some more time before
removing stuff/adding it to p-a-s how the users of other subarchs are
thinking about this.

Yes, that's the real bottleneck atm for m68k. We need more porters whereas
we have a nice number of buildds now.

I think it would be ok for some less used, but long building packages when
those would be crosscompiled (if this is ok with policy and the
ftpmasters/RMs).

For building packages it doesn't matter if it's been build by a coldfire or
a real m68k, but as coldfires mainly being used in embedded devices, I doubt
there are many OpenGL capable coldfire systems, but I've to admit that I'm
totally new to coldfires...
