 **  "Real Mode" operation refers to U2/Uturn chip operation.
 **  U2/Uturn were designed to perform coherency checks w/o using
 **  the I/O MMU - basically what x86 does.

 **  Drawbacks of using Real Mode are:
 **	o outbound DMA is slower - U2 won't prefetch data (GSC+ XQL signal).
 **      o Inbound DMA less efficient - U2 can't use DMA_FAST attribute.
