Keep in mind that the GX1's are ancient. The only issue with the CS4236 
is that it sits on the ISA bus on the motherboard so the PCI scan done 
by modern linux versions won't find the right settings.  If you supply 
the module parameters it should still work.  There is probably some 
pattern to the MAC address range on these boxes.  Is there a way to do a 
setting in lts.conf that applies to a range instead of a specific address?

And one great thing about Dell is that they make bios updates and other 
downloads available forever.  The original GX1 bios had a problem with 
PXE booting, but you can still get the update to fix it.
