Intel Matrixraid on amd64

[Benny Goemans]

Hi,

I'm running 8.0-release (i386) on a Asus P5WDG2 motherboard with integrated 
Intel Matrixraid (software raid) controller. Everything runs fine in this one.

Since I've noticed 64 bit support for the Nvidia driver I've been trying to 
install the AMD64 8.0 version. During install dmesg shows my hard drives and 
raid drives (ar0, ar1)  perfectly, just as it does in the i386 version. But 
when I enter sysinstall it can't locate my drive(s). It just doesn't find a 
single drive, no arN but also no hdaN (which do show up in dmesg).

Has anyone seen this behaviour before and is there some kind of solution? 
Maybe some parameters to sysinstall, extra kernel modules to load that are on 
the install disk or something?

Kind regards,

Benny Goemans

ps. I'm currently redownloading the iso file for the cd and will check its 
checksum to make sure I don't have some bizarre bad download
