Hi,
First of all congratulations for the good work on Broadcom chipset.
I tried the latest GIT kernel to try out the BCM 4328 chip support.
I remember reading some where that It loads firmware successfully.
Please find below the results.
uname -r = 2.6.25-rc7-custom
uname -m = x86_64
uname -v = #2 SMP Mon Mar 31 08:32:18 BST 2008
Without the NPHY support card failed to initialize.

[ 2056.834077] b43: probe of ssb0:0 failed with error -95
In order to compile the driver with NPHY support I had to cheat the
Kconfig for b43.

Card is recognized as "Broadcom 4321 WLAN found"
Although lspci output states otherwise.

Also when the driver module is loaded Radio is turned off and requests
to turn on the radio using hardware switch,
this is an Apple iMac and I don't have any hardware switch to turn on
the Radio. Does it require some user space utility
or driver does not contain support for the Radio yet?
wlan0 shows up in the system after loading the driver.

I am aware that support for this chipset is work in progress, I would
be happy to help in testing.
