Well, color me surprised. And lucky. :) While I was testing 'swsusp'
(S2D mode), I managed to figure out that there was some CPU-related
module that was creating a problem. A little experimentation, and
/voila/ - I discovered that the 'acpi_cpufreq' module (which isn't very
useful to me anyway) was the one gumming up the works. At this point,
I've run "echo disk > /sys/power/state" more than 10 times in a row from
a variety of configurations - "init=/bin/bash", booting to console with
a full load of modules, running X, X plus a PCMCIA card - and it's all
working so far. I'll definitely report if it starts acting stupid again.
If anyone has suggestions for edge-case testing (i.e., any kind of
situations in which S2D is likely to fail), I'd appreciate hearing about
them. By the same token, further suggestions for getting it working with
's2ram' would also be appreciated.
For the record, here's the relevant data for the current (working) state
of this laptop:
