The CLI call is bogus.
I note a commit I *just* made:
----------------------------
revision 1.49.2.4
date: 1999/07/10 18:36:59; author: nate; state: Exp; lines: +1 -2
- Remove un-necessary CLI statement from apm_int, which casues
suspend/resume to fail on at least some IBM Thinkpads.
[ FWIW, the cli call is also missing from -current ]

----------------------------
If the CLI is there, my box refuses to suspend. Apparently it was
removed from linux a while back, and like many software projects that
don't have usable history, the bug is now being re-introduced into Linux
again. :(
As far as the segment registers, we do an explicit save of them already
when we switch into VM86 mode, so it should be necessary to save them
twice.

I'd be interested to know if either of the patches did anything...
