My C3 Ezra has the PN133T (VT8606) chipset, the Nehmiah has the CLE266
(VT8623/VT8237) chipset.  These are not your normal mini-itx board by VIA.
They're both 3.5" single board computers by another OEM.

I eliminated all other processes, just matchbox.  I'll try your 
suggestion and run it as
non-root.  I'll also try to run with other window managers and see.  
This couls very
well be a hardware problem.  I think it's more than the DMA problem 
since my OS
is in-memory, hence no hard drive is being accessed when it runs.
