Everything works great, except if you use Intel SATA RAID (ICH5R). The kernel does not have software RAID drivers. You can install libata and the iswraid patch for kernel 2.4, but you have to resolve a loading order: iswraid(IDE driver) needs libata(SCSI driver) wich is loaded after IDE. Kernel 2.6 has SATA support, but still looking for RAID.
