it boggles my mind as well, but when I comment out the SMP lines in my config
file:
options SMP # Symmetric MultiProcessor Kernel
options APIC_IO # Symmetric (APIC) I/O
options NCPU=2 # number of CPUs
X goes bonkers, the screen randomly shifts back and forth a pixel or so.
But now that SMP mode doesnt slow down my internet connection
I am more or less fine. The little wiggle left is tolerable for the time
being.
The only thing I could think of is that the motherboard with the second cpu
not being used gets a voltage spike (or other uncleanliness) and that is
affecting
the video card. Or perhaps the 40 degrees cooler the thing runs without the
second cpu makes the video card unhappy :)
