OK, if this is the case (cannot use ~x86 and ~amd64 on the same
machine) then my impression, from the set of apps I'm running right
now, is there there is a lot of software I cannot depend on. There are
a large number of apps that don't work unless compiled with ~x86. If I
cannot use that then I cannot run maybe 30-40% of what I want to run.
Of course, I've not hit the problems you're describing. I've been
lucky I suppose.

Thanks. Interesting info.
