Make your kernel non SMP enabled. If it's the same hardware I have used, the cpu was changed to a x86 compatible microcontroller called Vortex86sx. If this is the case you will also need to apply a patch to allow for propper IDE and chipset functionallity to get IDE and USB, Ethernet etc to work. I ported the patch they have for download (earlier kernel version) to the current build, but unfortunatelly i'm not in the office for another 2 weeks, so I can't post it.
