To add a tiny bit of additional information to this one.
On my IBM Thinkpad T41p (Type 2373-GKG S/N 99-95BGD 04/12),
i see the following behaviour:

If you press "Access IBM" during BIOS boot, then "Start setup utility"
in the "Access IBM Predesktop Area", then Config->Power in the
"IBM BIOS Setup Utility", you can switch that feature off:
"Suspend when LCD is closed: [No Suspend]".
Of course, automatic suspend on closing the LCD is often useful,
but for your kind of trouble, disabling this feature might help.
On the other hand, i cannot confirm the result of your test.
If i switch to console mode (Strg-Alt-F2), log in, sudo to root,
kill xdm (such that i have gettys on ttyC[0235], am logged in on
ttyC1 and have a lonely blinking cursor on ttyC4), and then
close the LCD, the ThinkPad suspends alright. When i open the
LCD again, it resumes operation, displaying ttyC1 as before.

Indeed, in console mode, suspend/resume using Fn-F4 works for me, too.
As i fail to reproduce the particular problem reported by Mark,
i cannot comment on the advice given by [EMAIL PROTECTED]
> the "suspend via terminal" technique comes back always...
> I had four crashes when suspending from X
When starting xdm from the root command line, i just got the
following messages:
[EMAIL PROTECTED] # xdm

After that, suspend/resume in console mode still works, both by Fn-F4
and by closing and reopening the LCD. But when i switch to X (Alt-F5)
and try to suspend from there (using either Fn-F4 or closing the LCD),
several things happen:
1. The display of the X desktop vanishes.
2. For a fraction of a second, a pattern of broken white
lines is displayed.
3. Then i see the lone blinking cursor expected on ttyC4
when X is not running (hugh?).
4. The ThinkPad does NOT switch to suspend mode (the moon symbol),
but stays in active mode (the zig-zag-symbol below the LCD).
5. Strg-Alt-F2 and Fn-F4 have no visible effect any more.
6. BUT, having machdep.kbdreset=1, Strg-Alt-Entf still
initiates a proper shutdown sequence, even bringing the
console display back:
syncing disks... done
The operating system has halted.
Please press any key to reboot.
Thus, i strongly suspect that suspend is NOT crashing the OS,
but that instead this is merely (?) a problem with video modes.
But don't ask me for details, i do not feel fit to explain anything
about the switching of VGA video modes.
Is there anything i can do to help figuring this out?
