just FYI
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=99a700bcc75429ba84a672d04f0b650dcc5b3042

All these drives in manline linux (with patch above) are visible as separate devices
(separate controllers) while with proprietary driver you see one big device
(which is raid0 internally in fact)

I was able to mount it with mdadm with 64k chunk size later (with separate drives).

Its fw seems to be optimized for the raid0 case though...
