Thanks for steering me to bug# 6712. I may have found a solution to the
poweroff problem. 

By comparing my .config files for kernels-2.6.19.1, 2.6.20.11. 2.6.21.1 &
2.6.22.1, I noted that kernel-2.2.23.1 was the only one with a
config_pm_sleep=<y> option in addition to the config_acpi_sleep=<y> option.
Could these two sleep options be confusing the system at poweroff ? 

SHORT TEST:
I assumed the config_pm_sleep option was associated with APM & disabled APM at
boot with the apm=off parameter. This enabled me to run ACPI & actually
poweroff at shutdown.

Here is the boot command I used:
[EMAIL PROTECTED] ~]$ cat /proc/cmdline
BOOT_IMAGE=sata-2.6.23 ro root=801 hdd=ide-cd resume=/dev/sda5 splash=silent   
     apm=off

Tomorrow, I will re-build kernel-2.6.23.1 with both APM & ACPI but w/o the
config_pm_sleep option & see if the system will still poweroff at shutdown.
I'll let you know what happens.
