Here is the solution :-)

I booted the fedora HD as slave of the motherboard controller:

# lspci -v

[...]
02:0b.0 Unknown mass storage controller: Integrated Technology Express, Inc.
   IT/ITE8212 Dual channel ATA RAID controller (PCI version seems to be IT8212,
   embedded seems (rev 11)
        Subsystem: Integrated Technology Express, Inc.: Unknown device 0001
        Flags: bus master, 66Mhz, medium devsel, latency 0, IRQ 11
        I/O ports at a800
        I/O ports at ac00 [size=4]
        I/O ports at b000 [size=8]
        I/O ports at b400 [size=4]
        I/O ports at b800 [size=16]
        Capabilities: [80] Power Management version 2

# joe -w grub.conf

title Fedora Core (2.6.5-1.356)
        root (hd0,0)
        kernel /vmlinuz-2.6.5-1.356 ro root=LABEL=/ rhgb quiet selinux=0 ide2=0xa800,0xac02
        initrd /initrd-2.6.5-1.356.img


The formula: ide2=A,B+2
where A is the address of the first I/O port and B the address of the second I/O port plus 2.
(fedora HD as master on the master IDE port on the controller card)

Cheers,
Hannes.
