we have just installed a CentOS 5.5 on 320G6 with B110i controller. As you
correctly said, the CentOs shows both devices while booting w/o dd. However, as
we have found, contrary to what is said in release notes for the controller DD,
you must not dd it, however, just unzip it and place the .dd file on your flash
disk, preferrably formatted in plain FAT16(vfat). After that, boot up your
CentOS install disk with 'linux dd' option. CentOs will accept the dd file from
the flash disk w/o further complaints.

Note though, that even though the CentOs will install over the RAID1+0 virtual
volume, sda and sdb will still be shown in the device tree, although the B110i
will correcly write to both devices.
