Thanks, that was priceless advice. I reverted
da2c12a279ae225f3d4696f76cb3b32a5bec5bfb "[ARM] Clean up ioremap code"
and n2100 booted fine. I can now confirm Lennerts patch makes
r8169 work without any module parameter work on Thecus n2100.

With ioremap cleanup code and printascii, the kernel boot looks
like following:
