ACPI breaks network, old AMD K6, just FYI

[Michael Ross]

Hi,

i just installed 7.0-RC1 on an old AMD K6 machine,
and enabling ACPI breaks networking.

Trying to access anything but localhost, tcpdump does not see any packets  
at all.
Pinging a LAN machine leads to "sendo: no buffer space available" after  
about 100 packets.

Part of dmesg follows.
As mentioned in the subject, this is just FYI, I can run the machine fine  
with ACPI turned off.
