Update 2009-01-04: As Jose mentioned, the latest driver (ver. 5.10.27.12) no longer needs this patch!

If you have problem to compile Broadcom 802.11 Linux STA driver (version 5.10.27.6) on Kernel 2.6.27 and get error message like the following:

/home/ye/downloads/bcm4328/hybrid_wl/src/wl/sys/wl_iw.c: In function ‘wl_iw_get_scan’:
/home/ye/downloads/bcm4328/hybrid_wl/src/wl/sys/wl_iw.c:934: warning: passing argument 1 of ‘iwe_stream_add_event’ from incompatible pointer type

...

Then you need to apply the patch: hybrid_wl-5.10.27.6_patch-2.6.27

How to apply the patch:

1. Download the STA driver and the patch.
2. Extract the STA driver and switch to the root of source tree (where Makefile is located).
3. patch -p1 -E < path_to_patch/hybrid_wl_5.10.27.6_patch-2.6.27
