That would be the case on a hardware raid card. On a bios software fake
raid, linux ignores the bios and sees the hardware as it really is.

Yes. The linux software raid uses less cpu and runs faster.
The only advantage to the fake raid is that it works with windows (with
the right driver), so you could potentially want it when doing dual boot
between windows and linux and wanting raid in both. dmraid might work
with the intel bios raid, but isn't in debian's installer, and as far as
I know isn't really fully completed yet either.
