T23: Audio and ACPI/apm

[G. Vincent Castellano]

I have an IBM T23 laptop, previously running Red Hat 9, upgraded to FC3t2.

Should I be submitting my problems to bugzilla or discussing here first?

1. Audio sometimes needs to be re-inited

Sound worked fine out of the box on RH 9.  Now the audio is sometimes broken 
until I delete the stanza from /etc/sysconfig/hwconf and re-run kudzu.  Xmms 
gives its generic 'Couldn't open audio' box, and snd (the sound editor) just 
hangs when I try to play something.  Stanza from hwconf is:

class: AUDIO
bus: PCI
detached: 0
driver: snd-intel8x0
desc: "Intel Corp. 82801CA/CAM AC'97 Audio Controller"
vendorId: 8086
deviceId: 2485
subVendorId: 1014
subDeviceId: 0222
pciType: 1
pcidom:    0
pcibus:  0
pcidev: 1f
pcifn:  5

2. No hibernation on closed cover

In RH9, Power management worked only partway:  if I pulled the power before 
closing the cover the machine would hibernate properly.  If I closed the cover 
first and then pulled the power, it would *not* detect the 'power change' event 
and would run down the battery.  This was a quirk I learned to live with.

Under FC3t2 in the default config (no ACPI kernel param, apmd running) the 
machine apparently didn't recognize when it switched to battery power or when 
the cover closed, it happily converted battery power to heat energy in my 
backpack.  When I set kernel param acpi=on, removing and replacing the power 
plug gave the familiar chirps, but nothing else happened.  At bootup we have 
this in /var/log/messages:

I see Test3 is scheduled out today.  I'll load it up this weekend.
