Hi,
2.6.18 (2647) did not fix the pata dma-problem:
[root@helios ~]# hdparm -d /dev/hdc
/dev/hdc: using_dma = 0 (off) [root@helios ~]# hdparm -d 1 /dev/hdc
/dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) [root@helios ~]#
Or do I have to do some configuration change ?

You need a new enough kernel to handle the ICH6M SATA and PATA together nicely and the devices not to be in compatibility mode.
Alternatively build 2.6.18-rc4-mm2 and select the Intel PIIX/ICH driver from that without the "old IDE" PIIX driver and it should grab all the devices and put them under /dev/sda /dev/sr0 etc using libata.

I found that I had to set a flag for my laptop to use dma.
Google for ICH6 flags to set in grub.
I can play DVD's and videos from my HD or DVD player under FC4. :)
