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?
