By the tone of your post, I'd say it took you a while to get your 10v going. Sounds like you got it now though, good for you....
To answer your 2 points...
1. I didn't post that you should downgrade your bios to A04, because I didn't. I have 2 Mini 10v's, one with A05 and one with A06, both run flawlessly. Older versions of the netbook bootmaker needed A04 bios, but the latest doesn't.
2. I used HFS+ for both of mine, so that's what i posted. Whether it works for others or not, I can't speak to that.
I just posted what worked for... I apologize for not meeting your needs, with my post. I hope it helped others. Feel free to reply if you have any more comments/concerns...
