I do not know how netboot implements the uncompressor, but when
writing the code for etherboot, I noticed that accesses to the ROM are
extremely slow. That is why the compressed code is first copied to RAM
before uncompression starts. You should try to enable caching for the
ROM area and check if that makes a difference.
