There have been people that tried to put it into the mainline kernel, but that is now basically unmaintained code and I cannot compile a recent kernel for my platform. The long-term solution is to work to integrate required drivers into the mainline, but I work for a commercial company and we are launching a system soon which is running in an embedded style with this platform. The system is a TS-7800 arm based SBC from http://embeddedarm.com, the hardware is good, but unfortunately they have chosen to take a kernel version and make their own fork without making sure it gets updated. The ts7800 platform support in the current kernel does not appear to work, or I am too dumb to make it work ;-) The only good thing about this is that I do not have to run this board connected to the internet or any other untrusted source directly. Hopefully, I will get the time required this year to update the required components to the current kernel version and get it into the ARM arch, but honestly, I started developing a few drivers for this board and am not a linux guru (yet) so it is a daunting task to take up on my own. So yes I would like to move to a newer kernel, but it is not trivial. best regards, Wouter
