I'm curious whether it might allow me to use AHCI mode on a T60p laptop; right now I can't because in AHCI mode the Ultrabay hard drive device becomes invisible to Linux (although not to Windows, interestingly). I'm currently travelling and I don't carry the T60 around anymore, so I can't do the experiment right this moment, but given that this would allow the T60 to take advantage of ALPM if this works, it would be awfully tempting.... - Ted
