There are several settings. One setting has the _only_ option "IDE" 
(Mode?). Another settings has "IDE", "AHCI" and "RAID", I have it on 
"AHCI". On another page, I can chose between "Compatible" and "Enhanced", 
it's on "Compatible". This is the only setup in which the AHCI driver will 
be used (if generic_ide is not present).

Ok, I will make a bug report for this.

I removed "generic_ide", "ide_isa" was still there.

Well it's the good old "two drivers fight over same device" problem. I 
thought this was overcome with the new device manager, but maybe the 
problem is something else.
