I'd love to see some debug information in whatever path it was that was
silently failing, if we can.  It's so easy to miss places to add format
support.  (I see gallium doesn't use sargb images currently, but might
want this in the future, plus we're still missing an equivalent change
for 2101010 though I don't know if anybody's made it really work
anywhere on dri2 either)
