Because thare are no x86_64 versions of those Luke Macneil's packages I 
did follow this howto for building new kernel for my desktop machine.

And then of course this one.

I can boot, I can start jackd and ardour2 and I can play a year old 
short something.

And I can listen Radio Paradise vith VLC (network works, too) with that 
very latest linux vanilla kernel.

Of course I should work many hours with that kernel so I can say 
something about it's stability in Ubuntu Studio 9.04.

But yes, you can build it in Ubuntu Studio 9.04, if you like to try that 
one over Ubuntu's own.

And my desktop machine is pure Intel, no NVidia/ATI or something like 
that. And soundcard is Delta 66, integrated audio disabled by bios.
