As for the poweroff, you need APM or ACPI for this to work. APM doesn't
work in SMP mode (there's a line in the kernel messages you posted
saying as much), and you've just turned off ACPI for nearly everything.
You will probably have turned off hibernation support and *possibly*
some power-saving support when you disabled ACPI.

no idea how I could have disabled any flag to disable poweroff, any

Um. Let me try again.
Soft power-down isn't a standard part of a PC. Linux doesn't know how to
do it without APM or ACPI.
APM is out the question on SMP, due to the way it's designed.
So you need ACPI properly working for soft power-down.
You've added acpi=ht to the kernel boot flags.
This is defined as "ht -- run only enough ACPI to enable Hyper
Threading" (in /usr/src/linux/Documentation/kernel-parameters.txt). In
other words -- not enough to do soft power-down.
James.
Tnx James
I have moved the additional card to another PCI slot, but behaviour is
similar with same warnings/errors at start-up in var/log/messages and dmesg
I made also a trial stopping iptables and trying to connect with the SMP
kernel (and no acpi=ht option) but no connection established.
Now I have the following options:
1) use the standard kernel
2) use the SMP kernel with no internet connection (!!!!!)
3) use the SMP kernel with acpi=ht option at boot-time but no soft power-off
Of course option 2 is out of discussion
Shall I file a bug???
