I've changed the instructions for patching from Linux. The patch32lsb_330.zip package attached to post #1 now includes a script make-patch.sh which should simplify the process, especially now that there are multiple files to patch.

In short: Download and extract the patch32lsb_330.zip package, download the firmware archive into the same directory, edit the two .patch files, and run make-patch.sh

I have included a 32-bit Linux executable in the package, if you have a 64-bit system without the 32-bit compatibility libraries installed (or you just want to compile it yourself) then simply delete the patch32lsb executable and the script will compile a fresh one automatically (assuming you have gcc installed.)

I hope this is simpler and not just confusing for those who have already become used to doing it manually!
