Not for me, at least. I'm working with this configuration for more than
a year now without any bad side effects. What will happen, of course, is
that the kernel will copy data outside of the (then smaller) 2GB DMA
region to the 2GB DMA region, even for hardware that is fully 32-bit DMA
capable. Note that hardware that supports 64 bit addresses for DMA is
unaffected.
