I've hit the same issue on a Soekris 4801 with Voyage 0.6.1.

I found the following debian bug report
(http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=478317) provided the solution.

e.g.

remountrw
echo 'options ide_core options="ide=nodma"' > /etc/modprobe.d/ide
update-initramfs -u
remountro

reboot

It seems the issue is that options on the command line (via grub) aren't used
when modules are loaded from the initrd so you need to update the initrd to
include the options.
