Actually, I believe it's all generic ppc-code.  Of course if we
ever need more than 512MB, we will have a problem on macppc.
The issue is that the kernel KVA space starts to invade device register
space above 0x8000000 (USER_SR becomes 0xc so 0xc0000000).  The proper
way to fix this is switch macppc to the common ppc bus_space/bus_dma
code and use bus_space everywhere.
