That's pretty interesting!
It might even be that the "firmware" actually isn't real firmware but rather a set of config options. I have seen something like this for CSR based Bluetooth chips too. The settings would then also control the WiFi/Bluetooth coexistence which is probably the reason why it does not work w/o the blob in the Librems - the antenna switch does not switch it to the Bluetooth chip without it and thus the BT does not "see" any other devices around.
According to kernel sources our device is a
/* Atheros AR3012 with sflash firmware*/
The firmware it loads consists of two parts:
The "ramps" file is sysconfig the second is a RAM patch file for the in chip flash firmware.

Actually it is not the driver that is missing but a free firmware for the AR3k Bluetooth chip used.
You can see the failed firmware load attempt in the kenel messages:

Well, I can not say for all combinations but I have M.2 SATA + 2.5" SATA in my L13. In Seabios the M.2 SATA preceeds the 2.5" SATA drive, in Linux the 2.5" SSD becomes sda and the M.2 SATA ssd becomes sdb, this is what dmesg says:

The order that Linux detects the devices is also the other way araound, i.e. the M.2 becomes, if present, sda and the 2.5" SATA becomes sdb if M.2 is present. This should, if possible, also be reflected in Coreoot/Seabios. It is confusing when the first detected Coreboot/Seabios disk becomes the second one in Linux.
