Hi Ben, kernel 3.2.x is arrived in unstable and it's time to discuss our open point about b43-fwcutter package.

Below is a summary of list of changes that I would like to introduce with the new version of the package b43-fwcutter package: === - The majority of firmware-b43-installer's postinst is moved to a script (firmware-b43-installer) installed to /usr/bin. * root is required to execute the firmware-b43-installer script. - Hooks are installed to /etc/kernel/post{inst,rm}.d, which call the above script with an argument (the kernel version) during kernel image package installation and removal. - A kernel-specific directory is created at /lib/firmware if it does not exist. For example, /lib/firmware/3.2.0-1-686-pae is created when configuring linux-image-3.2.0-1-686-pae (the b43 subdirectory is created at this location during firmware extraction by the b43-fwcutter utility). - broadcom-wl 5.100.138 (firmware 666.2) is acquired and extracted for use with Linux 3.2 and later, broadcom-wl 5.10.56.27.3 (firmware 508.1084) is used for Linux 3.1 and earlier. * Providing firmware 666.2 allows BCM4331 based devices to be supported, as b43 received an initial implementation at Linux 3.2 (B43_PHY_HT was enabled at linux-2.6 3.2~rc4-1~experimental.1). - If the firmware-b43-installer script is not supplied with a kernel version argument (e.g. manual invocation by superuser), `$uname -r` is used. - chroot installs are still supported and are assumed to require the latest firmware; a message regarding use of Linux 3.2 for firmware 598 and up is displayed, firmware is installed to /lib/firmware without a kernel version subdirectory. === I already have some draft scripts for these modifications but before I would like to share these changes with you and kernel team. Please let me know if this solution could be acceptable or if there is a better solution. Thank you. Cheers, Fabrizio.
