tried a different approach... built a different array of two raid 0 disks on the nvidia controller of my motherboard. the installation process goes fine.. , the system is installed on the /dev/mapper/nvidia_ device.

At next boot the grub screen shows up, meaning the system di recognize the raid array.. the mandriva startup screen shows up , but freezes.

if booted in failsafe mode, it shows a bunch of errors in mounting the array volume ending in a kernel panic.. the install process did not ask for any driver, the raid controller was simply detected at the partitioning stage, but obviously something is missing..

any idea of how to gewt around this problem?
