b43 not working on rev 02 Broadcom Chipsets

[gururise]

Binary package hint: b43-fwcutter

I have a HP dv6000 notebook running Turion x2 processor. It uses a Broadcom BCM 4312 wireless chipset.

lspci gives:
03:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 02)

Upon installation of Hardy Release Candidate, I noticed the wireless was not working. The b43-fwcutter package was not installed, so I installed it via apt-get. Upon installation, it downloaded the 4.80.53.0 firmware and finished the installation. I rebooted, and still not wireless.

I noticed the b43 module was not loaded, so I did a: sudo modprobe b43
In the dmesg, I get the following errors:

Just another tidbit of information. Yesterday, I installed Fedora 9 Preview Release on the same laptop, and also used the b43-fwcutter. The wifi worked perfectly with Fedora 9, so I believe there is something in Ubuntu causing these unknown symbols.

I tried replacing the older broadcom firmware with the newer 4.150.10.5 version, and I still have the same problem.

Thank you for reporting this bug. I use the b43-fwcutter with the following card:
Network controller: Broadcom Corporation BCM4318.
I have no problems with this card.

I have 08:00.0 Network controller: Broadcom Corporation BCM94311MCG wlan mini-PCI (rev 01) on my HP nc6320.

After yesterday's installation of 8.04 RC, Broadcom was detected automatically and after Next->Next->Finish installation was Wifi working perfectly. So I cannot confirm this bug.

Ok, I believe I found the cause of this problem. It seems that Kernel 2.4.24 and lower do not have supporting drivers for the Broadcom 4311 and 4312 (rev 02) chipset.

After compiling and installing Kernel 2.4.25, my broadcom 4312 (rev 02) worked fine using the new drivers. Would it be possible to either:
1) Backport the new b43 driver subsystem from 2.4.25, which supports the newer rev 02 chipset
-or-
2) Get a 2.4.25 kernel (possibly in Universe) for Hardy

This will affect a majority of new HP Laptop users that are running AMD processors.
