Unfortunately, the patch doesn't seem to work with a buildworld build (I was doing make from within the directories). This is related to a hack I do of copying zfs.c into the efi loader directory so it can be built with fPIC. The build system seems to get tripped up in mkdep as a result. Could someone with more knowledge of the build system give me some pointers here? Otherwise, is all set for testing.

I was missing the busdma 9 part and was passing physical address directly to the hardware. I'll look into the busdma interface of the kernel and use it instead.
