Grub2 + SiI 3114 PCI card: disks not detected by grub.

I have moved my Windows 7 drive from an onboard (ICH10) SATA port to a SiI 3114 based PCI card.
All 4 disks on the SiI 3114 PCI card work as expected once kernel / initrd has loaded.
Grub2 cannot see any drives on the SiI 3114 PCI card at boot time, ergo chainloading to (hd7,1) fails with "no such disk".
Doing a 'ls' from the grub command line @ boot confirms hd0 - hd6 present, but no mention of hd7 - 10.

Details from system once booted:

============================= Boot Info Summary: ==============================

ls -l /dev/disk/by-label/Win7

(hd10)  /dev/sdk

grub-probe -d /dev/disk/by-label/Win7 
ntfs

Relevant part of /boot/grub/grub.cfg:

insmod biosdisk
insmod pc
insmod vbe
insmod gfxterm

insmod mdraid
insmod ext2
insmod ntfs

menuentry "Windows 7 Ultimate" --class "windows" {
    #search --no-floppy --label Win7 --set root
    set root=(hd7,1)
    chainloader +1
}

As can be seen grub-probe / grub-mkdevicemap finds hd7 - hd10 on the running system, so am I missing something simple? a module needed for the SiI 3114 card perhaps?
Google comes up pretty much blank on grub2 + siI 3114, anyone managed to succesfully chainload to a drive on one of these cards?

Cheers,

Steve.
