Hardware RAID controllers

[willmc]

Does anyone have any experience using hardware RAID controllers in Yellow Dog (or any other PowerPC Linux distribution)? I've got an old Power Mac G4 (Yikes!) 400MHz sitting around that I'd really like to throw a few SATA disks into and mirror them for some nice network storage, but there seems to be a complete lack of hardware RAID solutions for PPC linux. Everything either relies on BIOS or x86-compiled closed-source binaries for configuration.

Anyone know of anything out there that might work?
