I guess it depends on whether you can get the chipset up fast enough.
It's a 400 page datasheet, some would definately say that
implementing code for that in very short time is heroic, but you may
be more used to it, and manage well. :)

Likely yes, but it depends on how many things you must have compiled
into the initial kernel. Try compiling a kernel as you like it and
look at the size of arch/i386/boot/bzImage, or use LZMA to compress
vmlinux. It should be max 1Mb-32kb. You may want to investigate
linux-tiny as well.

Good, you save the space for the VGA BIOS in the flash then, and
don't neccessarily have to implement support for the graphics stuff
in the 965.

I think SATA would be faster, simply because USB means at least one
more layer of code between physical disk and filesystem driver.

Hard to say, it depends on your skill really. But it IS a tight

I think LinuxBIOS is more stable than any commercial BIOS, and that's
just one of it's advantages. :)
