You should be able to compile the kernel for PII and not have problems on
the PIII boxes.  At least compile for 586, sheesh.  :-)

Even if they had totally different NICs you could just compile both into the
kernel and whichever one was there would be found and used as eth0...

Very very carefully...

I *think* you could:
1) Make an XF86Config-4 for the GX1 and copy it to /etc/X11/XF86Config-4.gx1
2) Make an XF86Config-4 for the GX110 and copy it to 
   /etc/X11/XF86Config-4.gx110
3) in /etc/init.d/rc.local put something like:

if /sbin/lspci | grep "Intel Corporation 82810E"; then
  cp /etc/X11/XF86Config-4.gx110 /etc/X11/XF86Config-4
else
  cp /etc/X11/XF86Config-4.gx1 /etc/X11/XF86Config-4
fi

(You'll have to look at the output of /sbin/lspci yourself to figure out
what the right thing that's *different* to check for would be; if you're
really clever you could do a nested if so that if it doesn't look like a
gx110, you check if it looks like a gx1 and if it doesn't look like a gx1
you give it a fairly generic 640x480 VGA configuration.  The "82810E" is
what's in the Dell OptiPlex GX110 I'm sitting at, so that very bit of script
just might work.)
