hi Jeff,
this patch is used to set the SATA controller back to AHCI mode when ATI SB700 is set 
as combined mode or legacy IDE mode by BIOS, without this patch, just like ATI SB600, 
the SB700 SATA device will fail in these two modes.

BRs,
henry

+AD4- Besides those modes in ATI SB600 SATA controller, ATI SB700 supports one more mode:the combined mode.

+AD4- The combined mode is a Legacy IDE mode used for compatibility with some old OS without AHCI driver, 
+AD4- but now it is not necessary for Linux since the kernel has supported AHCI.

hmmmm.  The patch looks OK, but your description seems to indicate that
the patch is not needed?
