Hmm, well I can boot from the IDE device as it actually detects grub on 
the MBR, so it does switch to IDE at boot time?

The controller on my device is a SM322TF which is a compact flash like 
IDE controller. If one would put the IDE port in flash mode, the docs 
talk about communicating directly with the flash chips, which is 
impossble with the controller. Also, in IDE mode, hdparm tells me many 
things about the IDE device, so why would I want it in flash mode?

Ah! well I still have your coreboot.rom which I will give a whirl soon. 
Could I bother you for your .config so I can possibly tweak it?
