PCI-E SATA on Asus RT-N16 router?

Question

ASUS

I apologize for the misunderstanding, I was half asleep and missed so much that I managed to write this question on the blog. They even downvoted relatively humanely. But the question remains open.
There is an Asus RT-N16 router, it has an unsoldered Mini PCI Express port.
According to the documentation from Broadcom, it is intended for additional Wi-Fi.
I soldered the controller for SATA under the ExpressCard, it lights up with a blue diode, as expected.
The question remains: how to build the necessary kernel modules to make this good work?
Architecture: MIPSel
SATA adapter: NoName (in Windows it gets up without drivers, it is defined as Generic ...)
And in general, has anyone dealt with PCI Express on architectures other than Intel?

Have you tried searching on wl500g.info ? If there is such information somewhere, it is there.
PS: What firmware is on the router?
