[BUG] FC5/FC6 does not support ATI SB600 SATA

[Conke Hu]

ATI/AMD SB600 SATA controller supports 4 modes:
    legacy IDE
    native IDE
    AHCI
    RAID
The ahci driver in FC6 tries to claim all 4 modes of SB600 SATA, but
fails in legacy IDE mode.   and FC5 does not support any mode at all.

Now the root cause is found and patch created. My question is, is it
still possible to merge the patch to FC5/FC6 kernel (since the final
release comes out)?

Looking forward to any reply! Thanks!
