Silicon Image SiI 3124 and 3132 RAID controllers

[Leslie Jensen]

I'm trying to install FreeBSD 8-RELEASE on a machine with an Abit 
aw8-max MB. This MB has a built in SiI 3132 RAID controller. I also have 
an addon card with a SiI 3124 RAID controller.

The problem is that I can see the 2 disks and the RAID1 set that I want 
to use for the system if I connect the disks to the built in 3132 
controller. But if I connect the disks to the 3124 controller and create 
a RAID1 set, only the disks can be seen.

I need to be able to use both controllers because I've got four disks 
that I want to build a RAID5 set on one of the controllers.

Can anyone shed some light on this. Via Google I've read some articles 
about these controllers and I'm aware that I might have to rethink 
because of lacking support for the 3124 controller.

I've read in the ata man page that parameters can be added to 
/boot/device.hints but I'm not sure how to handle this during installation.
