Problems with Silicon Image, Inc. PCI0680 Ultra ATA-133 Host Controller

Hello devs,

Upgrading to GRUB 1.98 I fell victim for what appears to be an
incompatibility between GRUB and this controller.

Two drives are attached the controller, configured for mdraid in Linux.
Upon installation of grub-1.98 and the subsequent reboot I was faced
with a "no such disk"-error when accessing md0.
Accessing the drives directly gave "out of disk" errors.

With the help of #grub on freenode I tried running grub-emu and also
starting up grub using qemu. None of these aproaches showed any
problems, and could see and access the drives without problems.

After *much* fiddling I ended up re-arranging my drives so that I am no
longer using this controller. And now everything is just dandy again.

If there is an interest in making this card work, I can offer modest
testing, but more importantly I can donate the card to a GRUB developer.
I no longer have need for it, and if I could contribute back this way
I'd be glad.

(bear in mind that I am not subscribed to this list)

The details of the card:

The kernel module might also shed some light as to where this card is
not behaving as it should?
