Hi, all b43 developers and users,
  I've just today found the b43-dev mailing list,

and through archives saw some problems reported with "BCM4312 802.11b/g",
http://lists.infradead.org/pipermail/b43-dev/2010-June/thread.html

I also have a problem with "BCM4312 802.11b/g [14e4:4315]" on my HP
Compaq CQ40 notebook,
on openSuSE-11.2 distribution, (may be identical with someone, sorry,
I didn't check,)

the default b43 driver just hang the whole system, when loading; so I
must blacklist it,
and use the linux-sta driver (wl.ko) (closed-source code by Broadcom)
worked well on it;

even if I compiled the latest linux-2.6.34 kernel source, the b43
would still hang the system;
my kernel compilation and installation are correct because I have
compiled for many other machines;

Here is the detailed lspci data about this card:

Hope someone would tell me I misused something and there is a way to
use the open source b43 driver;

There are some recent changes that fix problems with b43 hanging the
system at load. To use them, you should get the compat-wireless package
from the Packman repository. If that does not fix your problem, then you
should try the latest kernel (2.6.35-rc3) from the wireless-testing git
tree. If that does not fix the problem, then let us know here, and we will
figure out some additional debugging steps.

I have compiled master-2010-06-24 last Sat, and it really worked well till now,

http://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git

See soon next release will support broadcom4312 with b43 perfectly,
and some distribution enable it default,

Thanks to our developers,

Well, in the next release (2.6.35), AFAIK there will be no way to
selectively disable BCM4312 support.
