I agree with some of the other posters. You're being REAL brave running that 
on a 1.3 beta. On a server, I would have definitely gone with 1.2 (and been a 
bit sweaty about the palms doing that -- Gentoo's strength is not stability 
right now.)  I hope most of those 127 sites belong to friends of yours that 
are forgiving about outages.

The one recommendation I would make would be to compile your kernel for all 
the new stuff as well as the old (I'd do it with modules), and if in doubt, 
make it a module. (You'd have to have support for modules compiled in, of 
course.)

I just had to replace a motherboard myself recently, and there were all kinds 
of little oddities I had to clean up. Having support for everything in the 
kernel will minimize your downtime getting the new box up. (I assume you want 
it up as soon as practical.)

One other little tidbit from recent personal experience. Be sure to check 
things out with hdparm once you get the new motherboard in.  My new one had 
one of my hard drives running at about 4 MB/s. After I turned on the usual 
stuff, it ran about 40.5 MB/s.  Your mileage will almost certainly vary, but 
it's always worth checking.
