Hi, I was messing around with a new machine the other day when I decided to
install
FreeBSD 3.0-CURRENT. I've got a celeron 300a in it running at 450Mhz. Since
the Kernel decided not to pick this up, I've patched it. I am including it
in this
message. I'm not promising anything, but it works great for me ;}
