I think it would it be really nice to update the wiki for the DSM 5.2 Update 5. I tried following the instructions step by step from an Ubuntu VM using the latest bromolow toolchain, without much success. I was building the kernel to include module support for pata_jmicron, and I do get to build the kernel alright, but the kernel is like 3M in size. The kernel included in the XPEnoboot USB stick is like 12M. And I get to build the module ok, but it can't be insmoded to the USB stick kernel.
If anyone knows how to build a wiki for people that just want to build drivers with the latest toolchains, I think it would help a lot of people and maybe minimize the driver requests... but it could be that I'm just not that familiar with kernel building and linux...
