That's actually incorrect.  I use IDE on Footbridge because it works
loads with my CY82C693 board.  I never submitted the patches which make
CY82C693 work on ARM though...

However, the CY82C693 must not be allowed to use DMA (which is why the
ATA driver can't be used) - if it does, it locks the PCI bus.  It's
a hardware incompatibility between some PCI devices and the Footbridge.
