[CentOS] Installing CentOS on RAID PATA not SATA - A8V

I'm trying to install CentOS 4 on an A8V on the
PATA/Raid drives on the Promise controller.  The
Promise controller is recognized (sata_promise), but
the PATA drives are not recognized.  Base on this
thread

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=147303

it seems that there is a patch which was merged in
2.6.11 to get pata working.

Any ideas how to proceed?


Thanks in advance
