I've investigated with some SSB debugging:
[ 4895.592113] ssb: Core 0 found: ChipCommon (cc 0x800, rev 0x16, vendor
0x4243)
[ 4895.592125] ssb: Core 1 found: IEEE 802.11 (cc 0x812, rev 0x0F,
vendor 0x4243)
[ 4895.592135] ssb: Core 2 found: PCMCIA (cc 0x80D, rev 0x0A, vendor 0x4243)
[ 4895.592145] ssb: Core 3 found: PCI-E (cc 0x820, rev 0x09, vendor 0x4243)
[ 4895.612051] ssb: Found rev 1 PMU (capabilities 0x02A62F01)
[ 4895.620727] ssb: SPROM revision 8 detected.
[ 4895.620732] ssb: MAC ff:ff:ff:ff:ff:ff
[ 4895.642495] ssb: Sonics Silicon Backplane found on PCI device
0000:10:00.0
I added the ssb: MAC line, sprom extraction seems incorrect for this
device (is ssb up to date enough in wireless-testing for this device?).
