I don't think that is the problem. The output from booting the kernel
says "unregistered net_device" as well:

[    9.236512] libertas_sdio: Libertas SDIO driver
[    9.245261] libertas_sdio: Copyright Pierre Ossman
[    9.762777] libertas_sdio mmc0:0001:1: (unregistered net_device):
00:19:88:11:db:67, fw 9.70.7p0, cap 0x00000303
[    9.792377] libertas_sdio mmc0:0001:1: wlan0: Marvell WLAN 802.11

Thanks anyway,
