I have some experience (~2 months) with FC4 64-bit and in it is a stable
distribution with a good performance. I've used the 32-bit version
first(then the processor runs in emulation mode) and the difference with
the 64-bit version is considerable.Especially X benefits of the 64-bit
but also other programs (e.g. compiling). However, although many
packages are already adapted for 64-bit, many more are not. Also many
plugins for browsers don't work, e.g. Macromedia flash. If ardour isn't
adapted for 64-bit, the possibility exists you cannot compile it as e.g.
pointers, but also memory addressing etc. must be changed. I expect the
compiler(s) to be fitted with switches for compilation for different
architectures but I am not familiar wth it.

See my remark above.
