This fix inspired me to finally try to convert my Sun Ultra5
(sparc64) with a CMD646 [1095:0646 rev 03] to libata.
With pata_cmd64x the machine has so far survived a usual
boot/mrproper/reconfig/make/install/reboot kernel update
cycle without any issues, and performance seems to be the
same as with the old IDE driver.

Note that the olde driver has MWDMA fixed, and the new one has it still
borken, yet MWDMA2 is the mode you're using.
