That's what we're doing on Linux and that seems the best compromise. On
Linux there are many different kernel flavors where it is being worked
on to reduce their amount. I propose -486 for older PCs and 686-pae for
newer PCs. See [1] on more discussion about the minimal required processor.

I am not sure if FreeBSD has drawbacks to use a SMP flavored kernel on a
traditional legacy system with one CPU only. If yes there perhaps should
be a -smp version for each too.

Generally it seems an upstream bug to me though if the kernel crashes on
such a system. Regarding D-I I guess there is no easy way to tell in
advance whether the system needs a PAE kernel or not, and the fact the
wrong choice crashes does not make it any more easy to choose a kernel.

Is it really safe to assume every system with more than 4G RAM supports
the long mode for sure?
