I am unsure of 5.3-Release, but I have been able to suspend pretty
reliably (with a few patches) with 5.3-Stable. I just tried with
-current and my display never blanked or turned off and on resume, zzz
never terminated. I had to CTRL-C to get a prompt back. (This is with
the standard ata driver, not MkIII.)

It's possible that I missed the acpi_video_dpms patch when I built my
last kernel. I just moved back to current last week and I've built a
bunch of kernel in a hurry, so I might have missed it. In any case, it
looks like there might be a slight regression. New kernel shortly.

Oh, it's an IBM T30.
