Nope, sun4u just means it's an ultrasparc processor (not all of which
are 64-bit capable). You can boot either the 32-bit or the 64-bit kernel
on most Suns (both are installed generally). We use isainfo to tell us
what type of applications the running kernel is capable of running. If it
says 64-bit *and* 32-bit we know that it's capable of running either
(meaning it's at 64-bit), but if it just says 32-bit then that's all she
can take.
Similar deduction is done on HP-UX 11.X systems as well (`getconf
KERNEL_BITS` returns 64 or 32).
