those are two different chipsets, the CX700M2 is for the C4 family of 
ITX mini boards, while hte 82C7xxx stuff is their older northbridges for 
desktop systems...  

googling for that, I saw mention that Via has a linux patch for it, and 
apparently all it does is add a new PCI vendor/device ID so the existing 
drivers recognize the new chip.  you can probably find the CX700M2's PCI 
vendor/device ID with lspci(8)
