"2) there is some fundamental problem that makes it difficult/impossible to

Fakeraid not working in linux is a driver issue. And yes, for some of
the more common fakeraid manufactures you can find linux drivers.
Promise raid cards being one of them. If you go to your MB
manufacturer website you might find linux drivers, but i doubt it.
I used to pay for expensive true hardware raid cards then I switched
to software raid and never looked back. The extra overhead is not
noticeable and recovery/management is easier than hardware raid IMO.

There are moves towards making these RAID arrays visible to Fedora (I
can't diagnose why yours wasn't), but what you end up with is Linux
software RAID using the disk structures that the BIOS set up -- almost
exactly what you've got now, it's just that the BIOS knows about it too.
It's arguably better *not* to go with the BIOS-based RAID, and just go
for Linux software RAID, simply because then your RAID isn't dependent
on the BIOS of the machine in question, and can be moved to a different
sort of PC without problems.
Hope this helps,
James.
