Subject: tg3 does not recognize BCM57788

Hi,
    I am trying to get BCM57788 (14e4:1691) device to work on an Intel board. I get the following error in my dmesg. I am trying with the latest tg3 driver from  net-next (http://git.kernel.org/?p=linux/kernel/git/davem/net-next-2.6.git).

[56902.029119] tg3.c:v3.105 (December 2, 2009)
[56902.029128] tg3 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
[56902.029137] tg3 0000:01:00.0: setting latency timer to 64
[56902.032038] tg3 0000:01:00.0: PME# disabled
[56902.033051] tg3 mdio bus: probed
[56902.033052] eth%d: No PHY devices
[56902.033295] tg3: Problem fetching invariants of chip, aborting.
[56902.033381] tg3 0000:01:00.0: PCI INT A disable

It seems to be the same problem as reported here  https://bugzilla.redhat.com/show_bug.cgi?id=525966
Except that it is BCM57788. I tried to load the broadcom.ko module before tg3 but I still get the same error.

And here is the complete lspci -vvxxx of my Broadcom device
