You found a bug in hw/i386/Kconfig :)

I noticed this while working on refactoring ICH9 for the Boston board,
but didn't expect the Q35 machine would suffer the same issue.

The quick fix is:

-- >8 --
diff --git a/hw/i386/Kconfig b/hw/i386/Kconfig
@@ -80,7 +80,7 @@ config Q35
     select PC_ACPI
     select PCI_EXPRESS_Q35
     select LPC_ICH9
-    select AHCI
+    select AHCI_ICH9
     select DIMM
     select SMBIOS
     select VMPORT
---

I'll send a patch.

Regards,

Phil.
