SATA ICH5 not detected at boot, mm-kernels

[Fabio Coatti <cova@ferrara.linux.it>]

Hi all; It seems that problems like this has been already reported, but not 
exactly the same, so maybe thsi can add some infos. Otherwise, sorry for the 
noise.

Starting from 2.6.19-rc1-mm1 and up to rc4-mm2, at boot the kernel is unable 
to detect two sata disks, connected to a ICH5 controller. Latest mm working 
kernel seems to be 2.6.18-mm3; 2.6.19-rc4 works just fine.

On rc-4 (vanilla) the log is this:

With -mm kernels, I see only the third disk, but attached to a different 
controller (output from rc4 vanilla):
