I have three comments about updating modules in linux.
1. The toolset runs good enough in wine to do the manual update procedure.
2. There is a utility called TlkEdit that is a java app so it runs natively. It is more manual and a bigger learning curve than using the toolset but it can be used for editing modules. You could use it to edit the module.ifo file to set pointers to the hak files and tlk file, set the scripts that are loaded into cache and set the event scripts. You can use it to extract the contents of prc_consortium.erf and import them into the module. What it won't do however is edit or compile script files. You can easily export the scripts and edit them in a text editor but I haven't gotten a working compiler in linux. I have gotten nwnnsscomp.exe working in wine but that is not a pure native solution.
3. The PRCModuleUPdater is a great utility, it makes updating modules quick and easy. It is a .net application but I haven't been able to get it to work in mono. It should not be hard to fix the code so that it is mono compatible. If there are any interested developers who are willing to tweak the code so that it works in mono, all us linux users would be very appreciative.
[In regards to people having upper case issues with the downloaded modules, remember ./fixinstall is your friend. I had the same issue when downloading custom portraits.]
