Please allow me to be offensively blunt for a moment.
So, the situation seems to be:
1. The work of the suspend developer who engages the users who put
effort into making suspend work on their hardware (bless
their addled little heads) often doesn't meet kernel standards,
or isn't well enough documented to prove the real *need* for
the features and/or hacks that have happened to get actual
users' systems sleeping and running again.
2. The swsusp maintainer continues in the belief that as long as
their are no bug reports in kernel bugzilla or crossing the
(relatively obscure) swsusp mailing lists, it has zarro boogs
and meanwhile works on the fourth implementation of suspend
support in as many years. It's in CVS on sourceforge. There's
no documentation whatsoever.
3. There's another guy who appears to be doing a lot of work, so I
shan't leave him out. Like the two developers previously
mentioned, he seems to be working pretty hard on the whole
thing. The previously mentioned fourth suspend implementation
seems to be largely his doing, for good and for ill.
4. "Everybody" knows suspend doesn't work on Linux without a huge
amount of tinkering, deep magic, and dead chickens. Only
Gentoo users seem to bother; everyone else waits for Ubuntu
12.04 wherein suspend will "just work". The Gentoo users all
use swsusp2, as it contains the hacks to work around:
5. All the suspend developers blame the lack of power-management
support in drivers for the inablility of Linux to properly
suspend on anything that doesn't support APM.
6. Getting proper power-management support in Linux device drivers
is not a priority; drivers without any power management support
whatsoever should not only be accepted -- they should be merged
without comment or complaint.
How is working suspend support ever supposed to happen?
