PATCH 1/1 libata: Fujitsu AMILO Pa 2510 can't do 64bit DMA either
This is the third SB600 system which can't do 64bit DMA. Add it to blacklist.

This is bad because we can't backport this to -stable and broken 64bit DMA makes these systems unusable for kernels released without the following blacklisting. I think we should disable 64bit DMA for SB600s in -stable. Any objections? Shane?
