You are really spending your money on such an uncertain thing? Well, that is either courageous or ... well, foolish
Indeed the manual says something about
"Operating System: Windows XP, Windows 7 and Linux" but reading shows limited Windows support (Vista not mentioned, not that Vista would be good for anything...), no BluRay for XP and Linux was mentioned with x86 (so probably no amd64 support).
99,9 % of the pages show Windows procedures and problems. "Linux" is just mentioned 2 times without any further hint. X.org or something not at all.
It's your money, I wish you luck but I am sure that you'll find out the many issues soon.
And I wouldn't spend any money on VIA anymore. Just had years of pain with their stuff (well, mainly the GPU side, the rest was so-so) I'll stay away from them.
