Change default kernel config

I'm unable to boot with the default kernel, since "BIOS Enhanced Disk Drive calls determine boot disk" is enabled.

One may wonder why is it enabled in default distro kernel anyway. Here a note
from kernel config:

"This option is experimental and is known to fail to boot on some obscure configurations. Most disk controller BIOS vendors do not yet implement this feature."

Maybe its just me, but I really dont consider my configuration as obscure :-)

It would be great if this was removed from the default kernel unless there is a reason for it to be there?

The problem occur when I have disks attached to the one of Promise controllers.
