Details:

I am building a network appliance based on a VIA EPIA-style motherboard with
a CompactFlash card for storage, connected through a generic CF to IDE
adapter.  GRUB will boot from a USB adapter but not from the IDE adapter.

I built a chroot'ed Gentoo image on my host machine and copied the install to
the CF card using a USB adapter.  I then appropriately modified the device
map, and GRUB installed successfully into the MBR.  However, upon installation
into the appliance via the IDE adapter, I just get "GRUB GRUB GRUB".

The BIOS detects the CF card reliably.  I have tried full auto-detection,
forced CHS geometry, and forced LBA; all give me the exact same error
condition.  The appliance boots to a Linux kernel successfully if I pull the
CF card out of the IDE adapter and attach it to the appliance via a USB
adapter.  Linux reports lost interrupts on hda when booting to a USB CD-ROM on
the appliance with the CF card in the IDE adapter.
