    I have an idea.  Please tell me if this is way off base.

    Why don't we just create a postfix out of the kernel name by default?
    So if you 'make installkernel KERNCONF=BLAH' you will get a
    /boot/kernel.BLAH and /boot/modules.BLAH ?
    So, for example, a GENERIC kernel would be installed as
    /boot/kernel.GENERIC and /boot/modules.GENERIC.
    We would then have a loader variable which defaults to 'GENERIC' in
    loader.conf, telling the loader which kernel to boot.
    How does that sound?

Install a kernel:
make installkernel KERNCONF=MYCONF
Install a second kernel, for example a SMP one:
make installkernel KERNCONF=MYSMPCONF KERNPOSTFIX=.smp
Install a kernel and modules somewhere else than /boot (like a VKERNEL):
make -DNO_MODULES installkernel KERNCONF=VKERNEL 
DESTKERNDIR=/var/vkernel/boot

I put the examples here to show that it does not really get that 
confusing. At least I don't think so and it gives all the options one 
might want.
On the other hand I like the idea of making it even more simple. If 
KERNPOSTFIX is not defined by the user we could set it to .${KERNCONF} 
and we get the behaviour suggested above.
