@Stefan,

there is something funky in your Makefiles, without wasting too much time I just hardcoded a couple of changes so that it would install and at least initialise (see attached patch).

Apr  5 19:15:13 desktop kernel: [ 1987.808748] ACPI: PCI Interrupt 0000:00:0e.0[A] -> GSI 19 (level, low) -> IRQ 19
Apr  5 19:15:13 desktop kernel: [ 1987.808755] PCI: Disallowing DAC for device 0000:00:0e.0
Apr  5 19:15:13 desktop kernel: [ 1987.819500] phy0: Selected rate control algorithm 'pid'
Apr  5 19:15:13 desktop kernel: [ 1987.881851] udev: renamed network interface wmaster0 to eth1

The bad news is that it still doesn't solve my wireless problem:
