I have a Broadcom BCM4313 wireless card which requires the brcmsmac driver. In the 3.2 kernel, enabling BCMA disables this driver, with the result that my wireless card no longer works.

The stock debian kernel seems to resolve the issue with their patch bcma-Do-not-claim-PCI-device-IDs-also-claimed-by-brc.patch:

bugs.debian.org/cgi-bin/bugreport.cgi?bug=649567 (Debian bug 649567) contains some discussion of the relevant issues as well. Could this or something similar be applied to liquorix to re-enable the brcmsmac driver?

This patch will be in the next 3.2 kernel (1.dmz.5).
