The old Intel PIIX is know to have DMA problems, I never intended to 
support it, but the current code (from luiqi IIRC) was found to be
sufficient IF the BIOS did its job right. I seems that we have a 
BIOS here that doesn't setup things the way they should be, and the
DMA setup fails because of that. Is there any way you could upgrade
your BIOS ??
