That's an odd remark :-).

If it should be supported but dmraid isn't finding it, send dmraid
-tay -vvv output to the list, along with any device-mapper error
messages in your syslog, and an indication (from dmesg typically) on
whether your drives has HPA.  Linux has seriously broken HPA handling.

If your chipset is as you suspect unsupported by dmraid, you should
send the metadata from your drives, along with a description of the
BIOS configuration (array name, type, size, is it broken?, etc.).  If
you need help finding the metadata, speak up.

There's also the slightly faster and more efficient way of fixing it yourself.
Take a look at the dmraid source code, it's concise and well-written.
