Sorry if this sounded as if I was against improvements of suspend.
That was not my intention.

But as long as there are driver problems, suspend as a whole can not be
called solid. The core itself might be solid or not, but without working
drivers this doesn't buy users much.

A user might be impressed by a progress bar on a nifty image, but if one
or more of his drivers have problems with suspend the user won't get a
good impression of Linux.

How many driver problems with suspend are buried in emails and
Bugzillas (will problems like kernel Bugzilla #6035 ever be debugged?)?
