We take a vanilla kernel with rt11 patches from Ingo Mollnar. Here are the section of my boot messages

If I set libata.dma=0 then it complained about missing symbols (but not with it enabled!). This was a clean SUSE kernel from Factory, with only the ATA patch applied with a few hand-merges (pata_mpc52xx.c has had a line of whitespace removed at some point, but otherwise identical).
