chipset "NVIDIA® nForce 570 SLI MCP"

Hi!

Since last year v2 is (almost?) running on the Gigabyte GA-M57SLI-S4. 
This board uses chipset
"NVIDIA® nForce 570 SLI MCP" (see 
http://www.coreboot.org/GIGABYTE_GA-M57SLI-S4_Build_Tutorial
or 
http://www.gigabyte.com.tw/Products/Motherboard/Products_Overview.aspx?Produ...)

As a newbie my first question is, of course, a stupid one: the "MSI "K9N 
SLI Platinum" uses the same chipset (see 
http://global.msi.com.tw/index.php?func=proddesc&prod_no=251&maincat...).
Well, actually I would prefere another chipset, but what is the problem 
in terms of LinuxBIOS
to get this (MSI) board working/running LB (the same level as the 
Gigabyte one)?

Of course I kind of studied more than once the mailing list, the wiki 
and many relatet sites.
Please keep in mind, I'm an absolute beginner to LB an just wondering 
why. And I'm looking
to get into this holy stuff.

Anyway

thanks for the great work!
