Hi,
I experience the following problem: Setting the trap flag (TF) of the
EFLAGS register correctly calls the debug exception DE. However, the
DR6 register does not have the single step (BS) flag set.
This patch fixes things for me, and I think it deserves some more
attention given that it had no replies at that time and it's not in
the latest release.

I remember this getting submitted. which version of Qemu are
you running? 0.9.0 or 0.9.0-cvs?

Right, thanks. I couldn't find any view-cvs interface and the cvs
snapshot didn't download. I was using the 0.9.0 release, yes.
