Yes, they are. Ipaq had a wrong broadcast address though; but fixing it
didn't help.

Last message I get on my serial console (after about 30 pages of oopses):

  <0>Kernel panic: Attempted to kill init!
In interrupt handler - not syn

After that the system locks up completely.

But I'm getting closer to the solution - it seems to be framebuffer
related! If I disable framebuffer support in the kernel, I still get the
"spurious IRQ for DMA channel 5" message, but USB networking works!
