This bug has since been reassigned to aptitude. Solver limitations
in aptitude wrt t64 handling should not be considered release critical,
it makes no sense to remove aptitude from testing for it; there are
still plenty of other valid use cases that are unaffected by these
particular bugs, so I am downgrading it to important.
