Subject: bleeding edge kernels misidentify my Broadcom BCM4401-B0

Hi,

Recently, while using bleeding edge kernels (built from git pulls of
vanillas sources from kernel.org), my Broadcom BCM4401-B0 Ethernet
card, normally driven by the b44 driver, has stopped working.  Poking
around, I discovered that the card is no longer correctly identified;
it now shows up (with 'lspci -v' as root) as this bizarre device:

06:01.0 Network and computing encryption device: Broadcom Corporation Device 0010 (rev 02) (prog-if 10)
        Subsystem: Allied Telesis, Inc Device 0010
        Flags: fast devsel, IRQ 10
        Memory at d0000000 (32-bit, non-prefetchable) [disabled] [size=8K]
        Capabilities: [40] Power Management version 2

Using a stock Debian kernel (2.6.32-5-686), it shows up (and works)
correctly:

06:01.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)
        Subsystem: Acer Incorporated [ALI] Device 0090
        Flags: bus master, fast devsel, latency 64, IRQ 21
        Memory at d0000000 (32-bit, non-prefetchable) [size=8K]
        Capabilities: [40] Power Management version 2
        Kernel driver in use: b44

What on earth is this all about?

I tried another kernel I had lying around,
2.6.37-rc6-lizzie-00132-g55ec86f (built from kernel.org vanilla
sources), and it also works fine.  I can do a bisection if necessary,
but I figured I'd check here first.
