You told me that since I'm doing a read following a write to uncached memory,

No, I was talking about a write followed by a read, to the same location.
That's what I said. Read following write == write followed by read.
out_8 should be fixed to behave like the other accessors.
Ok, but I'm not using any of the I/O accessors, so this doesn't affect me.
I just need to make sure that the read is executed after the write, and that the read completes before I continue. So I should I put an isync between the write and the read, and a sync after the read?
