No need to appologise! I know you did your best to provide all the
useful details and that's what matters. Also, will this experience it
will be easier to detect similar cases in the future.

Thanks for the info.

I don't know whose's fault is that sw suspend doesn't work with mach64
dri (it could be sw suspend patch, mach64 drm, or the agpgart). I know
that radeon driver has suspend/resume support, but I think it's for
hardware suspend.

Since I'm quite busy ATM I'm inclined to just wait and see how things
go from here.
