Kernel virtual memory?

Could kernel use virtual memory hardware to make non-linear chunks of
memory to look linear? It seems to me that it could solve the problems
with memory fragmentation and DMA memory allocation.

DMA memory could be allocated by moving allocated blocks away from the
lower 16MB, and other parts of kernel could be made happy by changing the
page tables accordingly.

So, is this possible/feasible/too ugly to implement?
