The pata_amd module will do ok, except:

 - the CS5536 register values are not the same as those found on
   AMD74xx/8111.  So timings are slightly off.

 - cable detection doesn't work

I'm waiting for AMD to decide whether they prefer the MSR or the PCI
version before pata_cs5536 goes upstream.  

For now the belt-and-suspenders approach would be to use the patch
above.  I'd do that for a production system for sure.  Is it going to
make a significant difference on a net5501 tinker toy with a single
PATA drive?  Probably not...
