X-Fi is such a generic term these days with Creative.
There are non emu20k1/2 based X-Fi's that do NOT support HWMix.
The Phoronix post was probably referring to those cards and thinking
it applies to all of them as a result.

Just a peek in the source code would show you that the hardware SRC is
supported.
