Justin, Any chance of having the following commited to -CURRENT ? http://www.freebsd.org/cgi/query-pr.cgi?pr=43345 It may not solve the whole thing but it would allow us (I have a SiS651/SiS962 motherboard) to install FreeBSD "as-is", that is without any UltraDMA disabling or kernel sources post-installation patch. I am asking this because I dual-boot FreeBSD/WindowsXP and XP without DMA is even worse (if possible) than with it (regarding performance and CD burning).
