No, but I can confirm that the problem occurs with kernel-2.6.9-1.724_FC3
on a Thinkpad T41 (pretty consistently too).  Also did not occur with
earlier kernels.

Feel free to Bugzilla this one.  It does sound different from #140004 to
me.

You can experiment with settings in /etc/sysconfig/apmd, but I'm not sure
what to suggest trying.
