I double checked and it is indeed set properly to "AHCI mode" (instead
of "enhanced" or "legacy"). I also upgrade the BIOS and it still shows
up the same way.

Right, and it is operating nominally (as far as I can tell). When I
enabled the JMicron controller, interestingly enough it showed up as
"JMicron AHCI controller" when set to AHCI mode in the BIOS. There
doesn't seem to be any ill effect running with a generic AHCI vs.
Intel-specific AHCI driver.
Perhaps it's supposed to show up this way, I'm not sure. As I said,
this is purely cosmetic and just piqued my interest/curiosity as to
why it'd show in a "generic" fashion.
