After installing FreeBSD 7.0-rc1 on my Blade 100, I decided to take a 
stab at getting the on board audio to work.  The bit that prevents the 
driver from working is that bus_dmamap_load() fails when lowaddr is is 
not somewhere over 3GB.  The Trident cards apparently require the DMA 
address to be in the low 1GB.

Are there no bounce pages on sparc64?
