Side note: some distros end up unloading and reloading modules over suspend.

I wonder if perhaps your system does that, and then when it resumes it
has reloaded the sky2 driver, but without your manual "disable_msi=1"?

Because it sounds odd that it would work with the kernel command line
but not manually, and so I wonder if perhaps there's a hidden module
unload/load that causes that second case..
