Robert--
What does this mean for us as current and presumably long-term YDL
users. Does it mean that we can look forward to an Orange Puppy Linux
that avoids all these driver problems. Does it mean that the Church
of Linus has false doctrine, that microkernel architectures really
are superior?
Actually, while you are at it can you point me to a source that
explains how a kernel designed exclusively for old Intel instruction
set can be boogered around to sing so on PPC?
Best, Ted
