Welp, quick testing shows just compiling the kernel with -m68040 and
eliminating support for the older cpus from the kernel does bubkis for
perf.  It did however generate a couple interesting subtle breaks.

The first shows up at boot;
/var/log/messages:Jun 28 21:31:24 LC575 savecore: can't find device 0/0

Using the provided generic kernel, I don't get that.  I'm assuming the
generic kernel in the LC040 build is slightly tweaked, but not sure how.

The second gem occured during my benchmarking.

After doing a make clean fetch in /usr/pkgsrc/shells/tcsh, I proceeded to
do a time make.  Using the generic kernel, I get;
1051.052u 147.173s 21:14.37 59.4%       0+0k 38+1753io 229pf+0w

Using MY kernel, I get;
1052.466u 145.624s 21:12.02 348455.1%   0+0k 39+1750io 240pf+0w

Whats up with the percentage?!

I'm going to try rebuilding world next to see what happens.
