[ltp] -ac11 sound card, anacron, suspend errors on Thinkpad A20p

[Billy Harvey]

When using -ac11 (otherwise stable) I've noticed the following sound
card messages when unplugging or plugging in my Thinkpad:

The Anacron restart was curious, but I haven't noticed either of these
messages previously.  The "buttons" on TKMixer would cycle as if being
activated after this event too.  Restarting TKMixer solves both the
cycling problem and the sound messages.  This is repeatable, and the
AC'97 message doesn't occur if TKMixer isn't running.  The
Anacron message occurs with or without TKMixer's involvment.

Suspend has not worked for quite a while in the 2.4 kernel series (I
can't remember when it last did, but it *did*).  Anyone have a
APM/ACPI configuration for the 2.4 that seems to work?
