This seems to make my x86-64 box happier...

((second attempt at sending this -- first one seems

an attached .jpg screenshot))

With alt4_v2 applied, resume still fails,
but slightly differently from before.

This time, there's the initial blank-screen for 31 seconds,
then the backlight turns on and I can see the syslog scrolling
in the window where I left it, as before.

New, is that the disk activity LED is stuck-on,
and the error-recovery code is doing something
every 30 seconds or so.

Other than that, it's still dead -- disk I/O not working.

Can this patch be combined with Linus's one-liner
and still work on your machine?
