Well certainly intel RST (which is of course fakeraid), should work
with mdadm, but I have no idea if the installer supports that mode of
operation. I used to run a system with raid 1 that way (using intel
IMSM), and until recently, the initrd never did get starting it right
and always needed manual help. That did eventually get fixed.
Of course given that it is a fakeraid, it seems to me the obvious solution
(well workaround at least) (unless you are dual booting with windows
or something else that doesn't natively do software raid), would be to
just use linux software raid. After all it is software raid either way,
and using plain linux software raid has much better support, and there
should not be any difference in performance.
