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?
