Check out the supported hardware list. My Asus A8V Deluxe doesn't seem to run
into problems (getting FC3 to boot with a mixed PATA/SATA can be tricky, as
you have to jiggle drive boot priority in BIOS).

No, if you have x86_64 OS, you need the x86_64 packages. This might be less
packages, if you're hooked on livna & Co.

I don't think so.

x86_64 has some fresh blood dripping down edge of the blade. Most of things work,
but you'll see less support when you'll run into problems. E.g. you'll have
trouble getting 3d acceleration going with ATI's binary drivers with newish
Radeons. I've given up on my 9600, and installed an nVidia instead which
worked well. I've had build issues with openhbci stuff. Expect lots more
breakage if you're used to ./configure && make && make install litany.

Judging from

it seems to work.
