Some ancient Broadcom devices had one core per band, e.g.:
ssb: Found chip with id 0x4306, rev 0x02 and package 0x00
ssb: Core 0 found: ChipCommon (cc 0x800, rev 0x02, vendor 0x4243)
ssb: Core 1 found: IEEE 802.11 (cc 0x812, rev 0x04, vendor 0x4243)
ssb: Core 2 found: PCMCIA (cc 0x80D, rev 0x01, vendor 0x4243)
ssb: Core 3 found: V90 (cc 0x807, rev 0x01, vendor 0x4243)
ssb: Core 4 found: PCI (cc 0x804, rev 0x07, vendor 0x4243)
ssb: Core 5 found: IEEE 802.11 (cc 0x812, rev 0x04, vendor 0x4243)
This hardware model was dropped for newer devices handled by b43.

With this patchset I'm still able to use my BCM4321, so I guess it's
alright & safe :)
