Hi Jeff,
The libata driver cannot be loaded if a system has a CD-ROM drive
connected via SATA instead of PATA because this is not combined
mode and reserved no ports in quirk_intel_ide_combined() function.
I think SATA only (non-combined) && legacy mode should be treated
as same as such combined mode. How about following patch?
