As Nate also pointed out, you can do this already right now.  Say
``fd(0,a)kernel'' at the boot prompt, and away you go.

Also, i assume your answer was for question #2?  So this still leaves
question #1: what would break if we shipped `swap generic' kernels as
GENERIC?  The root file system is being adjusted automatically anyway,
swap and dump spaces are configured at /etc/rc time.  Except of
allowing -a, there's IMHO not much more difference to a `swap generic'
kernel then.

Never trust an operating system you don't have sources for. ;-)
